The commands module will help:

>>> import commands
>>> status1, result1 = commands.getstatusoutput('run my prog')
>>> status2, result2 = commands.getstatusoutput('run my prog again')

Your program output can be split into lines with 

>>> import string
>>> lines1 = string.split(result1, '\n')
>>> lines2 = string.split(result2, '\n')

And compared like this:

>>> while index in range(len(lines1)):
>>>    if lines1[index] <> lines2[index]:
>>>         print 'diference at', index
>>>         print lines1[index]
>>>         print lines2[index]
