I found this book that looks very good for beginning to learn a programming language, and in particular, Python.
[I am really sorry, but we don’t post external links here as we can’t control the content. For those who are interested, the reference is to a book called Think Python by Green Tea Press, available in various editions. Harry]
To make it easy to remember, the 1st edition is for Python 2 and the 2nd edition is for Python 3. You want 2, which
is to say you want 3. Got it? You want Python 3, book edition 2.
