Python Forum

There are free titles available from Springer about wide range of topics (read more: Free access to a range of essential textbooks from all disciplines)

Some Python titles available are listed below (there are also books about specific topics like AI, neural networks etc but one should look for them themselves):


A Beginners Guide to Python 3 Programming

Advanced Guide to Python 3 Programming

The Python Workbook

Python Programming Fundamentals

Data Structures and Algorithms with Python

Elementary Mechanics Using Python

A Primer on Scientific Programming with Python

I saw it in the German forum: https://www.python-forum.de/viewtopic.php?f=21&t=48163
