[Answered ]-Does IPython support python version 3.2.3? If not, why?

You can find some discussion about dropping 2.6 and 3.2 support here. One of the main reasons was that 3.2 does not support 2.x-style unicode strings – u"I love IPython!", while 3.3 and above do. This change made it possible to support 2.7 and 3.3+ in a single codebase.

Quickstart:

IPython requires Python 2.7 or ≥ 3.3.

If you need to use Python 2.6 or 3.2, you can find IPython 1.0 here.

PS:

The deadsnakes PPA has packages for old and new python versions:

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update
sudo apt-get install python3.3
