It's all in the standard library, the module is called -surprisingly-
- use random.uniform for the uniform distributions
- use random normalvariate for normal distributions
There isn't a Poisson distribution function, but there is a expovariate
function. I think you can get poisson like this, but take it with a
grain of salt because my probability skills are very rusty!
e = random.expovariate
acc = 0.0
for n in itertools.count():
acc += e(l)
if acc >= 1.0:
