Add print statements to understand what's going on, and then come up with your own variations. If you have a Github account, use this to showcase your variations. Not only is this essential practice, but it demonstrates your skills to others, including perhaps future clients or employers...</span>\n",

+# Fitness & Nutrition Planner Agent (Community Contribution)
+
+A tool-using agent that generates a **7‑day vegetarian-friendly meal plan** with **calorie/macro targets** and a **consolidated grocery list**. It supports **targeted swaps** (e.g., "swap Tuesday lunch") while honoring dietary patterns, allergies, and dislikes.
+
+> **Disclaimer**: This project is for educational purposes and is **not** medical advice. Consult a licensed professional for medical or specialized dietary needs.
+
+---
+
+## ✨ Features
+- Calculates **TDEE** and **macro targets** via Mifflin–St Jeor + activity factors.
+- Builds a **7‑day plan** (breakfast/lunch/dinner) respecting dietary constraints.
+- Produces an aggregated **grocery list** for the week.
+- Supports **swap** of any single meal while keeping macros reasonable.
+- Minimal **Streamlit UI** for demos.
+- Extensible **tool-based architecture** to plug real recipe APIs/DBs.
+
+---
+
+## 🧱 Architecture
+- **Agent core**: OpenAI function-calling (tools) with a simple orchestration loop.
+- **Tools**:
+  1. `calc_calories_and_macros` – computes targets.
+  2. `compose_meal_plan` – creates the 7‑day plan.
+  3. `grocery_list_from_plan` – consolidates ingredients/quantities.
+  4. `swap_meal` – replaces one meal (by kcal proximity and constraints).
+- **Recipe source**: a tiny in-memory recipe DB for demo; replace with a real API or your own dataset.
+
+---
+
+## 🚀 Quickstart
+
+### 1) Install
+```bash
+pip install openai streamlit pydantic python-dotenv
+```
+
+### 2) Configure
+Create a `.env` file in this folder:
+```
+OPENAI_API_KEY=your_key_here
+OPENAI_MODEL=gpt-4o-mini
+```
+
+### 3) Run CLI (example)
+```bash
+python agent.py
+```
+
+### 4) Run UI
+```bash
+streamlit run app.py
+```
+
+---
+
+## 🧪 Sample Profile (from issue author)
+See `sample_profile.json` for the exact values used to produce `demo_output.md`.
+- **Sex**: female
+- **Age**: 45
+- **Height**: 152 cm (~5 ft)
+- **Weight**: 62 kg
+- **Activity**: light
+- **Goal**: maintain
+- **Diet**: vegetarian
+
+---
+
+## 🔧 Extend
+- Replace the in-memory recipes with:
+  - A real **recipe API** (e.g., Spoonacular) or
+  - Your **own dataset** (CSV/DB) + filters/tags
+- Add price lookups to produce a **budget-aware** grocery list.
+- Add **adherence tracking** and charts.
+- Integrate **wearables** or daily steps to refine TDEE dynamically.
+- Add **snacks** for days slightly under target kcals.
+
+---
+
+## 🛡️ Safety Notes
+- The agent warns for extreme deficits but does **not** diagnose conditions.
+- For calorie targets below commonly recommended minimums (e.g., ~1200 kcal/day for many adults), advise consulting a professional.
+
+---
+
+## 📁 Project Layout
+```
+fitness-nutrition-planner-agent/
+├─ README.md
+├─ agent.py
+├─ app.py
+├─ sample_profile.json
+└─ demo_output.md
+```
+
+---
+
+## 🤝 How to contribute
+- Keep notebooks (if any) with **cleared outputs**.
+- Follow the course repo’s contribution guidelines.
+- Include screenshots or a short Loom/YT demo link in your PR description.

+# AI Property Rental Assistant
+
+An intelligent property rental assistant Jupyter notebook that scrapes real estate listings from OnTheMarket and uses a local LLM (DeepSeek R1) to analyze and recommend properties based on user requirements.
+
+## Features
+
+- **Web Scraping**: Automatically fetches property listings from OnTheMarket
+- **AI-Powered Analysis**: Uses DeepSeek R1 model via Ollama for intelligent recommendations
+- **Personalized Recommendations**: Filters and ranks properties based on:
+  - Budget constraints
+  - Number of bedrooms
+  - Tenant type (student, family, professional)
+  - Location preferences
+- **Clean Output**: Returns formatted markdown with top 3-5 property recommendations
+- **Smart Filtering**: Handles cases where no suitable properties are found with helpful suggestions
+
+## Prerequisites
+
+- Python 3.7+
+- Ollama installed and running locally
+- DeepSeek R1 14B model pulled in Ollama
+
+## Installation
+
+1. **Clone the repository**
+```bash
+git clone <your-repo-url>
+cd property-rental-assistant
+```
+
+2. **Install required Python packages**
+```bash
+pip install requests beautifulsoup4 ollama ipython jupyter
+```
+
+3. **Install and setup Ollama**
+```bash
+# Install Ollama (macOS/Linux)
+curl -fsSL https://ollama.ai/install.sh | sh
+
+# For Windows, download from: https://ollama.ai/download
+```
+
+4. **Pull the DeepSeek R1 model**
+```bash
+ollama pull deepseek-r1:14b
+```
+
+5. **Start Ollama server**
+```bash
+ollama serve
+```
+
+## Usage
+
+### Running the Notebook
+
+1. **Start Jupyter Notebook**
+```bash
+jupyter notebook
+```
+
+2. **Open the notebook**
+Navigate to `property_rental_assistant.ipynb` in the Jupyter interface
+
+3. **Run all cells**
+Click `Cell` → `Run All` or use `Shift + Enter` to run cells individually
+
+### Customizing Search Parameters
+
+Modify the `user_needs` variable in the notebook:
+```python
+user_needs = "I'm a student looking for a 2-bedroom house in Durham under £2,000/month"
+```
+
+Other examples:
+- `"Family of 4 looking for 3-bedroom house with garden in Durham, budget £2,500/month"`
+- `"Professional couple seeking modern 1-bed apartment near city center, max £1,500/month"`
+- `"Student group needs 4-bedroom house near Durham University, £600/month per person"`
+
+### Changing the Property Website
+
+Update the `website_url` variable in the notebook:
+```python
+website_url = "https://www.onthemarket.com/to-rent/property/durham/"
+```
+

+## Project Structure
+
+```
+property-rental-assistant/
+│
+├── property_rental_assistant.ipynb  # Main Jupyter notebook
+└── README.md                         # This file
+```
+
+## 🔧 Configuration
+
+### Ollama API Settings
+```python
+OLLAMA_API = "http://localhost:11434/api/chat"  # Default Ollama endpoint
+MODEL = "deepseek-r1:14b"                        # Model to use
+```
+
+### Web Scraping Settings
+```python
+headers = {
+    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36"
+}
+timeout = 10  # Request timeout in seconds
+```
+
+### Content Limits
+```python
+website.text[:4000]  # Truncate content to 4000 chars for token limits
+```
+
+## How It Works
+
+1. **Web Scraping**: The `Website` class fetches and parses HTML content from the property listing URL
+2. **Content Cleaning**: Removes scripts, styles, and images to extract clean text
+3. **Prompt Engineering**: Combines system prompt with user requirements and scraped data
+4. **LLM Analysis**: Sends the prompt to DeepSeek R1 via Ollama API
+5. **Recommendation Generation**: The AI analyzes listings and returns top matches in markdown format
+
+## 🛠️ Troubleshooting
+
+### Ollama Connection Error
+```
+Error communicating with Ollama: [Errno 111] Connection refused
+```
+**Solution**: Ensure Ollama is running with `ollama serve`
+
+### Model Not Found
+```
+Error: model 'deepseek-r1:14b' not found
+```
+**Solution**: Pull the model with `ollama pull deepseek-r1:14b`
+
+### Web Scraping Blocked
+```
+Error fetching website: 403 Forbidden
+```
+**Solution**: The website may be blocking automated requests. Try:
+- Updating the User-Agent string
+- Adding delays between requests
+- Using a proxy or VPN
+
+### Insufficient Property Data
+If recommendations are poor quality, the scraper may not be capturing listing details properly. Check:
+- The website structure hasn't changed
+- The content truncation limit (4000 chars) isn't too restrictive
+
+## Future Enhancements
+
+- [ ] Support multiple property websites (Rightmove, Zoopla, SpareRoom)
+- [ ] Interactive CLI for dynamic user input
+- [ ] Property image analysis
+- [ ] Save search history and favorite properties
+- [ ] Email notifications for new matching properties
+- [ ] Price trend analysis
+- [ ] Commute time calculations to specified locations
+- [ ] Multi-language support
+- [ ] Web interface with Flask/FastAPI
+- [ ] Docker containerization

+       "**Title:** Radio Wave Propagation Modeling under Precipitation and Clear-air at Microwave and Millimetric Bands over Wireless Links in the Horn of Africa  \n",
+       "**Author:** Feyisa Debo Diba  \n",
+       "**Supervisors:** Professor Thomas J. Afullo, Dr. Akintunde Ayodeji Alonge  \n",
+       "\n",
+       "## 2. Objective / Research Problem\n",
+       "The thesis investigates radio wave propagation modeling in clear air and precipitation conditions over wireless communication systems in the Horn of Africa, specifically Ethiopia. The research aims to address the attenuation problem caused by precipitation for systems operating at higher frequency bands.\n",
+       "\n",
+       "## 3. Scientific and Regional Background\n",
+       "The congestion of lower operating frequency bands has led to the rapid growth of utilizing higher frequency spectrum for wireless communication systems. However, the Horn of Africa, particularly Ethiopia, lacks comprehensive studies on propagation modeling under different atmospheric conditions. This research provides valuable insights for the region, contributing to the efficient operation of wireless networks.\n",
+       "\n",
+       "## 4. Methodology\n",
+       "The research uses three years of atmospheric data (temperature, pressure, relative humidity) from the National Meteorological Agency of Ethiopia and clear air signal measurements over terrestrial Line-of-Sight (LOS) links from EthioTelecom. Rainfall data from a Davis Vantage weather station installed at Jimma University, Ethiopia, are also used. The study applies the ITU-R model for refractivity gradient prediction and the Rice-Holmberg (R-H) model for one-minute rain rate distribution. A semi-Markovian model is used for rainfall event characterization and generation.\n",
+       "\n",
+       "## 5. Key Findings\n",
+       "The research derived radio climatological parameters for different rain and clear air fade models. It also proposed rainfall rate conversion factors for Ethiopian sites and developed rainfall rate and fade margin contour maps for Ethiopia. The study found that the sojourn time of spikes in every rain regime is appropriately described by Erlang-k distribution. The number of spikes of generated rainfall events and the corresponding sojourn times follow the power-law relationship.\n",
+       "\n",
+       "## 6. Conclusion\n",
+       "The research provides a comprehensive analysis of radio wave propagation under different atmospheric conditions in Ethiopia. The findings contribute to the understanding of the impact of atmospheric conditions on wireless communication systems operating at higher frequency bands.\n",
+       "\n",
+       "## 7. Limitations\n",
+       "The research is limited by the availability and quality of atmospheric and signal level data. The simulation models also have inherent assumptions that may affect the accuracy of the results.\n",
+       "\n",
+       "## 8. Future Work\n",
+       "Future research could focus on refining the models used in this study by incorporating more data and improving the simulation techniques. Studies could also be extended to other regions in the Horn of Africa.\n",
+       "\n",
+       "## 9. Real-World Applications\n",
+       "The findings of this research can improve wireless network planning and 5G deployment in East Africa. The models developed can also be used in link budgeting, which is crucial for the design and operation of wireless communication systems."

+    "## Overview\n",
+    "This notebook provides a workflow to automatically analyze websites, extract relevant text, and generate a short summary using a language model. Navigation elements are ignored, focusing on news, announcements, and main content.\n",
+    "\n",
+    "## Features\n",
+    "- Extracts relevant text from web pages using Selenium and BeautifulSoup.\n",
+    "- Generates automatic summaries using OpenAI's language models.\n",
+    "- Presents results in markdown format.\n",
+    "\n",
+    "## Requirements\n",
+    "- Python 3.8+\n",
+    "- Google Chrome browser installed\n",
+    "- The following Python packages:\n",
+    "  - selenium\n",
+    "  - webdriver-manager\n",

+    "- An OpenAI API key (project key, starting with `sk-proj-`)\n",
+    "- Internet connection\n",
+    "\n",
+    "## How to Use\n",

+    "   pip install selenium webdriver-manager undetected-chromedriver beautifulsoup4 openai python-dotenv requests\n",
+    "   ```\n",
+    "2. Add your OpenAI API key to a `.env` file as `OPENAI_API_KEY`.\n",
+    "3. Run the notebook cells in order. You can change the target website URL in the code to analyze different sites.\n",
+    "4. The summary will be displayed in markdown format below the code cell.\n",

Add print statements to understand what's going on, and then come up with your own variations. If you have a Github account, use this to showcase your variations.

The website is about Edward's interests in writing code, experimenting with Large Language Models (LLMs), and DJing, as well as his work in applying AI to help people discover their potential.\n",

+      "**Categories:**\n",
+      "\n",
+      "### What is the website about?\n",
+      "\n",
+      "The website is primarily about Edward Donner's personal brand, showcasing his expertise in AI and LLMs. It includes information about his work at Nebula.io, which applies AI to talent management. The website also features a \"Connect Four\" arena where LLMs compete against each other, as well as sections for learning more about LLMs and staying up-to-date with Edward's courses and publications.\n",
+      "\n",
+      "### To whom does the website belong?\n",

+      "### Practices to improve for better user experience:\n",
+      "\n",
+      "1. **Clearer navigation**: The website's menu is simple but not intuitive. Adding clear categories or sections would help users quickly find the information they're looking for.\n",
+      "2. **More detailed about section**: The \"About\" section provides a brief overview of Edward's work and interests, but it could be more detailed and comprehensive.\n",
+      "3. **Improved accessibility**: While the website is likely following general web accessibility guidelines, there are no clear indications of this on the page. Adding alt text to images, providing a clear font size and color scheme, and ensuring sufficient contrast between background and foreground would improve the user experience for people with disabilities.\n",
+      "4. **Better calls-to-action (CTAs)**: The website could benefit from more prominent CTAs, guiding users towards specific actions such as signing up for courses or following Edward on social media.\n",
+      "5. **SEO optimization**: The website's content and meta tags appear to be optimized for search engines, but a more thorough SEO analysis would help identify areas for improvement.\n",
+      "\n",
+      "Overall, the website provides a clear overview of Edward Donner's interests and expertise in AI and LLMs, but could benefit from some tweaks to improve accessibility, navigation, and CTAs.\n"

+    "## Project Overview\n",
+    "This project combines web scraping with OpenAI’s GPT models to summarize online training content. It extracts material from Microsoft’s **Quantum Computing Fundamentals** learning path, cleans it, and generates concise summaries per lesson as well as an overall course summary.  \n",
+    "\n",
+    "## Key Features\n",
+    "- Fetches and parses webpages using **requests** and **BeautifulSoup**  \n",
+    "- Produces summaries in multiple languages (e.g., English, Spanish, or any language) and at varying levels of detail (short, medium, detailed)  \n",
+    "- Summarizes individual lessons on demand or processes entire learning paths  \n",
+    "- Presents results as clean, structured **Markdown** directly in the notebook  \n",
+    "\n",
+    "## Tech Stack\n",
+    "- **Model**: GPT-4o-mini  \n",
+    "- **Language**: Python  \n",

+       "\n",
+       "### Supervised Machine Learning\n",
+       "\n",
+       "**Definition**: In supervised learning, the model is trained on a labeled dataset, meaning that each training example is paired with an output label. The goal is to learn a mapping from inputs (features) to the output labels.\n",
+       "\n",
+       "**Characteristics**:\n",
+       "- **Labeled Data**: Requires a dataset that includes both the input features and the corresponding output labels.\n",
+       "- **Objective**: The objective is to predict the output for new, unseen data based on the learned mapping from the training data.\n",
+       "- **Common Techniques**:\n",
+       "  - **Regression**: For predicting continuous values (e.g., predicting house prices).\n",
+       "  - **Classification**: For predicting discrete labels (e.g., spam detection in emails).\n",
+       "- **Examples**:\n",
+       "  - Predicting whether an email is spam or not based on various features (classification).\n",
+       "  - Forecasting sales figures based on historical sales data (regression).\n",
+       "\n",
+       "### Unsupervised Machine Learning\n",
+       "\n",
+       "**Definition**: In unsupervised learning, the model is trained on data that is not labeled, meaning that it does not have predefined output labels. The goal is to discover patterns, groupings, or structures within the data.\n",
+       "\n",
+       "**Characteristics**:\n",
+       "- **Unlabeled Data**: Works with datasets that only have input features without any associated output labels.\n",
+       "- **Objective**: The objective is to explore the data and find hidden patterns or intrinsic structures without specific guidance.\n",
+       "- **Common Techniques**:\n",
+       "  - **Clustering**: Grouping similar data points together (e.g., customer segmentation).\n",
+       "  - **Dimensionality Reduction**: Reducing the number of features while retaining essential information (e.g., PCA - Principal Component Analysis).\n",
+       "- **Examples**:\n",
+       "  - Grouping customers into segments based on purchasing behavior (clustering).\n",
+       "  - Reducing the dimensionality of a dataset to visualize it in two or three dimensions (dimensionality reduction).\n",
+       "\n",
+       "### Key Differences\n",
+       "\n",
+       "1. **Data Type**:\n",
+       "   - Supervised Learning: Requires labeled data.\n",
+       "   - Unsupervised Learning: Works with unlabeled data.\n",
+       "\n",
+       "2. **Goal**:\n",
+       "   - Supervised Learning: To learn a function that maps inputs to the correct outputs.\n",
+       "   - Unsupervised Learning: To identify patterns or groupings in the input data.\n",
+       "\n",
+       "3. **Applications**:\n",
+       "   - Supervised Learning: Typically used in scenarios where past data with known outcomes is available (e.g., fraud detection, image classification).\n",
+       "   - Unsupervised Learning: Used for exploratory data analysis or when the outcome is not known (e.g., market basket analysis, anomaly detection).\n",
+       "\n",
+       "In summary, the primary difference between supervised and unsupervised machine learning lies in the presence or absence of labeled data and the objectives of the learning process. Supervised learning aims to predict outcomes based on existing labels, while unsupervised learning seeks to identify hidden structures in data without predefined labels."

+       "   As a result, this part creates a set of unique authors from the list of books. Since sets automatically discard duplicates, if multiple books have the same author, that author will only appear once in the resulting set.\n",
+       "\n",
+       "2. **Yielding Values**:\n",
+       "   ```python\n",
+       "   yield from\n",
+       "   ```\n",
+       "   - The `yield from` statement is used when you want to yield all values from an iterable. It allows a generator to yield all values from another generator or iterable.\n",
+       "   - In this context, it will yield each author from the set created by the comprehension.\n",
+       "\n",
+       "3. **Putting It All Together**:\n",
+       "   What this overall code does is:\n",
+       "   - It generates and yields unique authors from a collection of books, ensuring that each author is listed only once and only for books that actually specify an author.\n",
+       "\n",
+       "### Purpose:\n",
+       "This code is useful in scenarios where you need to obtain a seemingly infinite generator of authors from a collection of books, processing each author one by one without creating a permanent list or set in memory, which can be beneficial for memory efficiency especially if you have a very large collection of books.\n",
+       "\n",
+       "### Example Usage:\n",
+       "Here’s a basic example of how you might use this in a generator function:\n",
+       "\n",
+       "```python\n",
+       "def get_unique_authors(books):\n",
+       "    yield from {book.get(\"author\") for book in books if book.get(\"author\")}\n",
+       "\n",
+       "# Example books list\n",
+       "books = [\n",
+       "    {\"title\": \"Book 1\", \"author\": \"Author A\"},\n",
+       "    {\"title\": \"Book 2\", \"author\": \"Author B\"},\n",
+       "    {\"title\": \"Book 3\", \"author\": \"Author A\"},\n",
+       "    {\"title\": \"Book 4\", \"author\": None},\n",
+       "]\n",
+       "\n",
+       "for author in get_unique_authors(books):\n",
+       "    print(author)\n",
+       "```\n",
+       "\n",
+       "This would output:\n",
+       "```\n",
+       "Author A\n",
+       "Author B\n",
+       "```\n",
+       "\n",
+       "In this example, `Author A` only appears once, demonstrating the uniqueness provided by the set comprehension."

+    "- Return only what the system provides; do not invent, infer, or extrapolate unavailable data.\n",
+    "- Never offer or advertise any feature the environment does not actually support. Avoid offering attachments, direct downloads, or full-text article retrieval unless the system explicitly provides those outputs.\n",
+    "\n",
+    "## Behavior Rules\n",
+    "- Stay professional and neutral at all times.  \n",
+    "- Clarify only when user intent is ambiguous; never guess.  \n",
+    "- Only disclose information the user explicitly requested.  \n",
+    "- Never explain system limits (e.g., API ranges, date limits) ever.  \n",
+    "- Summaries should be tight and relevant, not verbose.  \n",
+    "\n",
+    "## NEWS & HEADLINES\n",
+    "- When interpreting date-related or temporal reasoning requests (e.g., “latest earnings,” “recent news,” “Q1 results”) Call `get_current_time` to determine the current date.\n",
+    "- Present news/headlines in concise bullet lines when requested. Default recent-window behavior is internal; do not describe or expose internal default windows or limits to the user.\n",
+    "- If the system only returns headlines/summaries, present those and do not offer to fetch full-text or additional ranges unless the user explicitly asks and the environment supports that action.\n",
+    "\n",
+    "## FOLLOW-UP & CLARIFYING QUESTIONS\n",
+    "- If no matching stock symbol is found, ask the user to clarify the name or ticker. Mention you only support U.S. stocks. If they confirm the symbol but no data exists, state that no results were found.\n",
+    "- Never append unsolicited menus, multi-choice lists, or repeated \"Would you like...\" prompts at the end of a normal reply.\n",
+    "- Ask a single direct clarifying question only when strictly necessary to fulfill the user's request (for example: ambiguous company name or missing ticker). That single question must be the final line of the reply.\n",
+    "- If the user's intent is clear, proceed and return results. Do not request confirmations or offer options unless required to complete the task.\n",
+    "\n",
+    "## MISSING-DATA / NOTE RULES\n",
+    "- Do NOT call out missing/unavailable single fields unless:\n",
+    "  1) the missing field was explicitly requested by the user; OR\n",
+    "  2) multiple (>1) key metrics required to answer the user's request are unavailable and their absence materially prevents a useful answer.\n",
+    "- If condition (1) or (2) applies, include at most one concise \"Note:\" line naming the specific missing field(s) and nothing else.\n",
+    "- Otherwise omit any comment about single, non-central missing fields.\n",
+    "\n",
+    "## ERROR HANDLING\n",
+    "- If a company/ticker cannot be found: \"I couldn't find that company on U.S. exchanges. Please provide the ticker or a clearer company name.\"\n",
+    "- If partial results are returned: present available data and at most one short note: \"Some data wasn't available: <field1>, <field2>.\"\n",
+    "- If you do not know the answer, say plainly: \"I don't have that information.\"\n",
+    "\n",
+    "## ADVICE / DISCLAIMER (CONDITIONAL)\n",
+    "- Do NOT include an investment-advice disclaimer in normal greetings or factual replies.\n",
+    "- Show a single-line disclaimer only when the user explicitly asks for recommendations/advice or uses clear advice-seeking language (e.g., \"should I buy\", \"recommend\", \"what should I do\", \"financial advice\").\n",
+    "- Disclaimer text when triggered: \"I can't provide investment advice or buy/sell recommendations. I can provide facts and explain metrics.\"\n",
+    "\n",
+    "EXAMPLES (templates — follow exactly)\n",
+    "\n",
+    "1) Clear factual request (no unsolicited follow-up)\n",
