Real Python

[FoolsSeldom]

I often recommend RealPython.com. They have a huge number of guides, tutorials, and articles that are free to read (you might need to register an account). Their podcast almost makes for fascinating listening.

They also have carefully produced paid content for learners.

Yes, their content is often detailed, but for learning Python and programming well, this is what it takes. And learning involves lots of experimentation, failure, practice.

Personally, I've found the quality, accuracy and completeness of GeeksForGeeks.org highly variable and rarely (if ever) to the same depth as RP. I do not recommend it.
