[issue37708] Harmonize random.choice(s) behavior with random.sample on iterators

[Lex Flagel]

New submission from Lex Flagel <flag0010 at gmail.com>:

It would be nice to make random.sample and random.choice both have the same behavior with iterators. Currently random.sample accepts them happily, and whereas random.choice does not.  E.g.

> import random
> d = {'a':1, 'b':2}
> random.sample(d.keys(),1)
Out: ['a']

> random.choice(d.keys())
Out: TypeError: 'dict_keys' object is not subscriptable

random.choice could be redefined as follows to harmonize behavior, but I think the solution for random.choices maybe be more involved:

def choice(x): 
    random.sample(x,1)[0]
