[SLUG] python version

[David <david@xxxxxxxxxxxxx>]

I need to have python version 1.5.2

How do I tell what version I have? Is there a generic way of discovering
versions? 

At a superficial observation, it looks like I have two versions installed
(1.5 and 1.5.2) but I think <python> invokes the older version.

sorry for the dumb question

btw:

$ man python
No manual entry for python

David.
