Managing Secrets & Python Environments – The Real Endgame

What do .env files, virtual environments, and pip freeze have in common?

They’re the secret weapons of every Python dev who’s tired of leaking secrets and breaking projects with one rogue install.

In this slightly over-caffeinated but totally beginner-friendly finale, we’ll cover:

How to store your API keys and DB passwords the right way
How to use python-dotenv to automatically load them
Why your system Python hates you (and how venv fixes that)
The difference between installing requests inside and outside a virtual environment
And how to share your project setup with just one file: requirements.txt

By the end, you’ll have a secure, isolated Python workflow you can reuse in every project.

Whether you're building your first real app or just tired of ModuleNotFoundError gaslighting you — this one’s for you.

👇 Bonus challenge at the end if you want to test what you’ve learned.
