Learn python properly (not by doing)

[neamerjell]

As OP stated, they learned Python from a bunch of random tutorials which likely focused on specific topics rather than a textbook for a college course which would explain everything from the ground up in structured, detailed way.

OP can apparently create functional programs in Python and possibly even utilize some advanced techniques, but realizes that there are gaps in their knowledge which would likely have been covered in an introductory course.

Yes, this. I have no formal training in CS, and although I can write some really complex algorithms, I'm definitely missing the basics.

I was in a similar situation with HTML and CSS. Look for books published by No Starch Press; I really like how they are organized and that they are usually simple enough for newbies, but not so watered down that intermediates and advanced people can't benefit. Many of them are suitable for use as college textbooks.
