How to iterate through a sequence, grabbing subsequences?

I wrote a function that I suspect may already exist as a python builtin, but I can't find it: def chunkify(s, chunksize): "Yield sequence s in chunks of size chunksize." for i in range(0, len(s), chunksize): yield s[i:i+chunksize] I wrote this because I need to take a string of a
