MIT OpenCourseWare
MIT 6.00 Intro to Computer Science & Program

Under MIT OpenCourseWare, all the lectures are available on MIT youtube channel with handouts and associative study materials. Here is the play list for this course -

some presentation (and code samples) on Generators in Python? Generator Tricks for Systems Programmers 

Python E-Books - e-Literature to get you started and free to boot

1. Dive Into Python – The original but not the best anymore.  It taught me Python so I’ve got fond memories and a special place in my heart for it.
2. How to Think Like a Computer Scientist: Learning With Python – A newly revised edition of this book is due out in Feburary 2009 but its still worth taking a look at the original.
3. Text Processing in Python – I haven’t read it but I thoguht I’d add it for the sake of completeness.
4. Start Programming With Python – Its a relatively new project started by an enthusiast.  A hell of a lot has already been produced and its due to be finished by Xmas.
5. PLEAC Python – Its like a rapid-fire Python Cookbook with short, concise examples of how to solve a variety of low-level problems.  Form string manipulation to database access.
6. Non-Programmers Tutorial for Python – Its for non-programmers but its sometimes useful to read form a different point of view.  I find the perspective refreshing.
7. Python 101 – Part of a university course this goes through the fundamentals as well as providing exercises.
8. Thinking in Python Design Patterns and Problem-Solving Techniques – A mammoth title written by the great Bruce Eckel.
9. Python Standard Library – This is seriously showing its age as it was originally written for Python 2.0.  Although there’s updates they’re incomplete.  Its still worth a look though to get a good idea of the Python core.
10. Python Programming Tutorial – It looks okay, though nothing ground breaking.
11. Django Book – A book on Pythons greatest web framework.
12. Pylons Book – A book on Pythons 3rd best web framework.
13. Sockets Programming in Python – I found this over at Scribd which is fast turning out to be a great little site.  I recommend you look at some of the other books on offer once you’ve looked at this.
14. Python Network Programming – Heavy on theory and light on practice.  Still a worthy read when you need to sleep.
15. Advanced Python Programming – This is actually a 126 slide lecture given by a Chicago University lecturer.  Some good stuff in here.
