[issue18844] allow weights in random.choice

[Raymond Hettinger]

Raymond Hettinger added the comment:

I'm adverse to adding the generator magic and the level of complexity in this patch.  Please aim for the approach I outlined above (one function to build cumulative weights and another function to choose the value).

Since this isn't a new problem, please take a look at how other languages and packages have solved the problem.
