I don't know of any.

Write a wrapper function:

#Untested
def datetime24(*args):
     try:
         return datetime.datetime(*args)
     except ValueError:
         args = list(args)
         if len(args) >= 4 and args[3] == 24:
             if ((not args[4:5] or args[4] == 0) and
                 (not args[5:6] or args[5] == 0)):
                 args[3] = 0
                 yesterday = datetime.datetime(*args)
                 return yesterday + datetime.timedelta(1, 0, 0)
         raise

This catches the error raised by the datetime object. If the hour is 24 
and the minute and second arguments either don't exist, or are 0, it 
calculates the datetime from 0:00 instead of 24:00, then adds one day to 
it. Otherwise it re-raises the error.
