Invalid example at this page: https://docs.python.org/3.6/library/random.html

'.items()' is missed in the line below:

>> population = [val for val, cnt in weighted_choices for i in range(cnt)]

The correct variant:

>> population = [val for val, cnt in weighted_choices.items() for i in range(cnt)]

[serhiy-storchaka]

There is no mistake. weighted_choices is a list of pairs.
