Best online resource to learn Python? [closed]

Question

If you need to learn python from scratch - you can start here: http://docs.python.org/tut/tut.html - good begginers guide

If you need to extend your knowledge - continue here http://diveintopython3.ep.io/ - good intermediate level book

If you need perfect skills - complete this http://www.pythonchallenge.com/ - outstanding and interesting challenge

And the perfect source of knowledge is http://docs.python.org/ - collection of all knowledge

If you're a beginner, try my book A Byte of Python.

If you're already experienced in programming, try Dive Into Python.

I think Python Challenge is great.

It's not about learning Python (syntax) but presents you small and fun riddles. Solving the riddles is based on Python but you can use whatever fits (your calculator, bash scripts, Perl...). After you solved one, you get to see how others have solved it and can discuss the pros & cons of the different ways.

Very nice to get a feel for how things could be done (smart) in Python. This site works especially well if you know a bit about other scripting languages or the commandline, etc.

The tutorial at Python's homepage is a good place to start. Also, there are some screencasts here.

These are unvaluable online reference tools:

• Python 2.5 Quick Reference

• Python Side bar

Other online resources for beginners:

• A good python blog for beginners: http://www.learningpython.com/

• Python Video at Google Code
