>>> 'abcd'.endswith(['a', 'b']) Traceback (most recent call last): File "", line 1, in 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 'abcd'.endswith(('c', 'd')) True Suggest closing as out of date.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.
