How to make random numbers in python without the random module

http://en.wikipedia.org/wiki/Pseudorandom_number_generator

There is even a link to an algorithm with a psuedocode implementation.

Personally, I think you should find something else to work on. I think reimplementing established algorithms will provide little educational value.

Best way to create one is to not to.

Pseudo-random number generators are a very complex subject, so it's better off to use the implementations produced by the people that have a good understanding of the subject.

Python uses the Mersenne twister as the core generator. It produces 53-bit precision floats and has a period of 2**19937-1.
The underlying implementation in C is both fast and threadsafe.

You can of course look at all code for python.
