📦 Shared Library Matrix

Which Python libraries are used across directories:

Library	Advance	ML	DataAnalysis	OpenCV	Flask	RestApi	SystemDesign	Selenium	WebScrape	PostgreSQL	ChatApp
numpy		✅	✅	✅
pandas		✅	✅
matplotlib		✅	✅
flask					✅		✅
django						✅
selenium								✅
requests							✅		✅
beautifulsoup4									✅
psycopg2										✅
opencv-python				✅
tkinter (stdlib)	✅										✅
socket (stdlib)											✅
scikit-learn		✅

Source Directory	Depends On	Relationship
`Assignments`	`ABasic_notes`	Exercises reinforce fundamentals
`AdvancePython`	`ABasic_notes`	Builds on basic syntax & data types
`DataAnalysis`	`MachineLearning`	Uses NumPy, Pandas, Matplotlib
`Open CV`	`MachineLearning`	Uses NumPy for array operations
`ChatApp`	`AdvancePython`	Uses OOP + Tkinter from advanced module
`flask`	`AdvancePython`	Uses OOP patterns for app structure
`RestApi`	`AdvancePython`	Uses OOP for models/views/serializers
`SystemDesign`	`flask`	All tasks built with Flask
`project-automatic-facebook-poster`	`AUTOMATION WITH SELENIUM`	Same Selenium automation patterns

🚀 Getting Started

1. Clone the Repository

git clone https://github.com/Ktripathi2611/learningPython.git
cd learningPython

2. Create a Virtual Environment (Recommended)

python -m venv venv

# Windows
venv\Scripts\activate

# macOS / Linux
source venv/bin/activate

3. Install Dependencies by Module

There is no single global requirements.txt — install per-module as needed:

# For Machine Learning / Data Analysis
pip install numpy pandas matplotlib scikit-learn

# For Flask web app
pip install -r flask/requirements.txt

# For Django REST API
pip install django djangorestframework django-filter

# For OpenCV
pip install -r "Open CV/requirements.txt"

# For System Design projects
pip install -r SystemDesign/requirements.txt

# For Web Scraping
pip install requests beautifulsoup4

# For Selenium Automation
pip install selenium webdriver-manager

# For PostgreSQL
pip install psycopg2-binary

4. Launch Jupyter (for notebooks)

pip install jupyter
jupyter notebook

⚙ Environment Requirements

Requirement	Version	Used By
Python	3.10+	All modules
Jupyter Notebook	Latest	`ABasic_notes`, `AdvancePython`, `Assignments`, `MachineLearning`, `DataAnalysis`
PostgreSQL	12+	`postgresql/`
Chrome + ChromeDriver	Matching versions	`AUTOMATION WITH SELENIUM`
Firefox + GeckoDriver	Latest	`project-automatic-facebook-poster`
Webcam	Any	`Open CV/08_webcam.py`

🤝 Contributing

Contributions are welcome! Here's how to get started:

Guidelines

Fork the repository and create a feature branch:
```
git checkout -b feature/your-feature-name
```
Follow the existing structure:
- Each topic gets its own directory
- Include a requirements.txt if new dependencies are introduced
- Use Jupyter notebooks (.ipynb) for tutorials with explanations
- Use .py files for standalone scripts and projects
- Add a README.md inside complex directories
Naming conventions:
- Directories: PascalCase or snake_case (match existing style)
- Python files: snake_case.py
- Notebooks: descriptive_name.ipynb
Documentation:
- Add docstrings to all functions and classes
- Include inline comments for non-obvious logic
- Add Markdown notes (.md) alongside notebooks for quick reference
Security:
- Never commit real credentials, API keys, or passwords
- Use placeholder values and document what needs to be changed
- Add sensitive files to .gitignore
Testing:
- Verify all scripts run without errors
- Test notebooks from top to bottom (Kernel → Restart & Run All)
- For Flask/Django apps, confirm all routes respond correctly
