>>> 'abcd'.endswith(['a', 'b'])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: Can't convert 'list' object to str implicitly
>>>

it would be nice like in str.join
>>> ''.join(('a', 'b'))
'ab'
>>> ''.join(['a', 'b'])
'ab'
>>> ''.join({'a', 'b'})
'ab'
>>> ''.join({'a': 1, 'b': 2})
'ab'
>>>

No, but they take tuples:

>>> 'abcd'.endswith(('a', 'b'))
False
>>> 'abcd'.endswith(('c', 'd'))
True

Suggest closing as out of date.

It seems like a set would make more sense than a tuple. And if tuples, why not lists?

Not that it matters much, since I doubt it's worth changing in either case. It's easy enough for the caller to convert.
