I'd bank on re.findall in this case, but I think you'd have to time
each approach to be sure.  Just avoid the lambda cases....
Also note that the re.findall method as given probably does not return
a lone final character as a result, while some of the other approaches
probably do.  Presumably, since you didn't specify it, you are 
planning to ensure the input always splits evenly.
