# 🐍 Python Virtual Environment (venv) Basics
A **virtual environment (venv)** allows you to create isolated environments for Python projects — so dependencies from one project don’t affect another.
---
## 1️⃣ Create Virtual Environment
```bash
python -m venv venv
This creates a folder named venv with a self-contained Python environment.
2️⃣ Activate Virtual Environment
▶️ Windows (CMD / PowerShell)
venv\Scripts\activate
▶️ macOS / Linux
source venv/bin/activate
Once activated, you’ll see (venv) in your terminal prompt.
3️⃣ Install Packages
Use pip inside the activated venv:
pip install requests
Check installed packages:
pip list
4️⃣ Deactivate Virtual Environment
To exit the venv:
deactivate
5️⃣ Save and Restore Dependencies
Save:
pip freeze > requirements.txt
Restore:
pip install -r requirements.txt
✅ Check Python Path
which python
# or on Windows
where python
This should point to your virtual environment’s Python executable.
💡 Tip:
Each project should have its own venv to keep dependencies clean and manageable.
