– & gt; loc: [optional] location parameter. Default = 0
– & gt; scale: [optional] scale parameter. Default = 1
– & gt; size: [tuple of ints, optional] shape or random variates.
– & gt; moments: [optional] composed of letters [`mvsk`]; `m` = mean, `v` = variance, `s` = Fisher`s skew and `k` = Fisher`s kurtosis. (default = `mv`).

Code # 1 : Generating a continuous Gompertz (or truncated Gumbel) random variable

from scipy.stats import gompertz    numargs = gompertz.numargs [a] = [ 0.7 ,] * numargs rv = gompertz (a)    print ( " RV: " , rv)

Output:
