How Python Knows What You’re Importing 🤯 (sys.path + venv Explained)
🤯 Ever wondered how Python knows where to find your packages when you do import pandas or from math import sqrt?
In this short but powerful video, I’ll show you how Python searches for packages using sys.path, how virtual environments (venvs) change the game, and how it knows what functions to import from a module.
You’ll finally understand those mysterious errors like:
❌ ModuleNotFoundError
❌ ImportError
and how to fix them like a pro.
🔍 What You’ll Learn:
1. What is sys.path and how Python uses it
2. What happens inside a virtual environment
3. How Python finds specific functions inside modules
4. The real difference between global and venv installations
🔗 Useful Commands:
bash
Copy
Edit
python -m venv myenv
source myenv/bin/activate # or myenv\Scripts\activate on Windows
