I was using Python's random library today, when I started getting the same numbers in a row for a random integer.
In all likelihood, it was just a fluke - luck wanted me to see those numbers a few times in a row. But it planted a seed!
I could test if random.randint() really is behaving with an equal distribution over the long run...
26 lines of Python later, I have a fun little toy program that let me try it out myself.
Want to know whether the random library tends toward even distributions in the long run (i.e. 1,000,000+ iterations)? Download the code and play with it yourself!
