[issue40569] Add optional weights to random.sample()

[Henk-Jaap Wagenaar]

@rhettinger: I like this proposal.

@dheiberg: to me, it seems negative weights are explicitly not supported, from: https://docs.python.org/3/library/random.html#random.choices

"Weights are assumed to be non-negative."

Unless I am missing something. In my mind negative weights make no sense and the fact it produces garbage in your example is garbage-in-garbage-out.

Maybe an enhancement could be made (but it would be breaking for some abusing the behaviour you showed) for it to error (or do something sane? If such a thing exists) but that should be a separate issue.
