SICP is being rewritten to Python

http://wla.berkeley.edu/~cs61a/fa11/lectures/functions.html
These notes maintain the spirit of SICP by introducing the features of Python in lock step with techniques for abstraction design and a rigorous model of computation. In addition, these notes provide a practical introduction to Python programming, including some advanced language features and illustrative examples. Learning Python will come naturally as you progress through the course.
