The Python module random
contains functions for generating random numbers according to several common distributions.
Distribution | Python function(s) |
---|---|
Uniform | random() , uniform(a, b) |
Beta | betavariate(alpha, beta) |
Exponential | expovariate(lambda) |
Gamma | gammavariate(alpha, beta) |
Normal | gauss(mean, sigma) , normalvariate(mean, sigma) |
Lognormal | lognormalvariate(mu, sigma) |
Pareto | paretovariate(alpha) |
There are, however, a few common distributions not on the list above. Code is available here for the following distributions.
SciPy has a large collection of random number generation functions as methods on distribution objects. See Distributions in SciPy.
