All indentation was lost in your message, so I'm not quite sure; here it is again, just in case:

import itertools as it

def hasConsequent(aString, minConsequent):
    for _,group in it.groupby(aString):
        if len(list(group)) >= minConsequent:
            return True
    return False

Run it from a file instead of the command line and see if you get the same result.

I'm using 2.4:
>>> sys.version
'2.4 (#1, Mar 29 2005, 15:15:45) \n[GCC 3.3.3 (cygwin special)]'

I would be very surprised if something so crucial changed between 2.4.0 and 2.4.1. What does
[list(group) for _,group in it.groupby("taaypiqee88adbbba")]
return to you ?
