I haven't done any thing intentionaly.
I had done a sudo apt-get install python-mode expecting that I needed 
that for my Python work.
I then removed it using sudo apt-get remove, thinking that the version 
installed by Ubuntu might be causing the problem.
I now asume that the default python-mode must have taken over, but still 
same result.
I don't intend to use the alternative Python mode.
By the way here is the output of C-h k  for the diagnose.
M-a runs the command beginning-of-python-def-or-class, which is an alias 
for `beginning-of-python-def-or-class',
which is not defined.  Please make a bug report.

Thanks for your help John, I was on a similar line of thought and your 
advice made it even more confirmed.  Surprisingly though, grep returns 
blank.  No result.
I don't understand what must be going on.
Happy hacking.
