VirtualEnv & Basics Recap

Python VirtualEnv

Virtual environments isolate project packages. Create with python -m venv venv, activate, then pip install.

On Mac/Linux: source venv/bin/activate. On Windows: venv\Scripts\activate.

Real-life example: VirtualEnv is a separate kitchen for each recipe — spices from one dish do not mix into another.

# Terminal steps
# python -m venv venv
# source venv/bin/activate   # Mac/Linux
# pip install requests
# deactivate

Basics checkpoint — you covered

You now know syntax, types, collections, control flow, functions, modules, JSON, RegEx, errors, and environment setup.

Next: OOP, files, data libraries, Matplotlib, ML overview, DSA, and databases.

Real-life example: Basics are learning to walk — OOP and databases are learning to run marathons with proper shoes.

• Every core Python topic through VirtualEnv
• Practice on /mcq/python-mcq after each part
• Re-read sections with code and run examples locally
