New submission from David Kremer david.kremer...@gmail.com:
Could you please add the exact form of the distribution, because it's rather
confusing in the current form.
In this url, the role of k and theta is precised with a formula :

It seems that in
[http://docs.python.org/library/random.html#random.gammavariate] , alpha is
playing the role of k and beta is playing the role of theta.
But it's still not clear, because one can confuse beta with 1/beta and vice et
versa, like there is two usual representation for the gamma distribution
[http://en.wikipedia.org/wiki/Gamma_distribution]
[http://docs.scipy.org/doc/numpy-1.5.x/reference/generated/numpy.random.gamma.html#numpy.random.gamma]*
Please update the documentation to avoid this ambiguity.
I provide an indicative patch which is updating the doc string in random.py
