It has also been back-ported to work in Python 2.6. use numpy to generate many uint8's in one step, (there might be something better using internal functions without the randint-API), uniformity follows from randint's uniformity guarantees, not caring about different result-types of these functions, not caring about -1 vs. 0 (might be important in your use-case), (not even optimal compared to much more low-level approaches; MT used internally can be used as a bit-source, which does not need fp-math, like many other PRNGs!). randomize was removed, because it was just an alias to random.seed.
