This is the my new "Python" page.
Python for AIX
Probably you are looking - right now - for one (or both) of these versions.
Further, you don't need yum to solve your RPM hell. Just use the AIX native install manager - installp.
Prefer YUM, maintaining a second run-time environment - then I encourage you to visit IBM, BULL and Michael Perzl's sites for their packaging. These sites have python in RPM packaging.
The choice is yours!
