Python 101 by Michael Driscoll

Learn how to program with Python 3 from beginning to end. My book is made primarily for beginners. However, at least two-thirds of it is aimed at intermediate programmers. You may be wondering how that works.

From the author:
“Today I am releasing my first book, Python 101, for free for 48 hours. Python 101 was written as an introduction to the Python programming language. While it is intended for beginners, some have claimed that they needed more hand-holding than this book provided for them. So I currently recommend it as an introductory and intermediate book for developers that are looking to learn Python.”
