Difference between python 1 and 2

Question

Just out of curiosity, but did python 2 do something important for python 1? and if so, then what?

Answer 1

Summed up from http://docs.python.org/whatsnew/2.0.html :

• Unicode Objects
• List of concepts
• Advanced setup
• Recycling
• *args and **kwargs unpacking arguments

Answer 2

Changes in the code base were for Unicode, list context, string methods, extended assignment and garbage collection statements. The change without code was that they use SoucreForge for the development process.
