[issue18844] allow weights in random.choice

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Other languages have no such handly feature as generators. NumPy provides the size parameter to all functions and generates a bunch of random numbers at time. This doesn't look pythonic (Python stdlib prefers iterators).

I believe a generator is most Pythonic and most handly solution of this issue on Python. And it is efficient enough.
