Difference between python 1 and 2

Question

Just out of complete curiosity, did Python 2 add anything major to Python 1? And if so, what?

Answer 1

Summarised from http://docs.python.org/whatsnew/2.0.html:

• Unicode objects
• List comprehensions
• Augmented assigment
• Cyclic garbage collection
• *args and **kwargs argument unpacking

Answer 2

The changes to the codebase were for unicode, list comprehensions, string methods, augmented assignment operators, and garbage collection of cycles. A non code change was that they are using SoucreForge for the development process.
