(Python) algorithm to randomly select a key based on proportionality/weight

Question

I\'m a bit at a loss as to how to find a clean algorithm for doing the following:

Suppose I have a dict k:

>>> k = {\'A\': 68, \'B\': 62, \'         


        

Answer 1

one should also look at this link

make two list for k, say xk and yk

from scipy import stats
custm = stats.rv_discrete(name='test', values=(xk, yk))
custm.rvs(size=1)
