range.index() takes exactly one argument

[ilai-deutel]

range.index() does not accept start and stop arguments (the documentation was fixed in python/cpython#13075):

>>> range(1, 9).index(1, 0, 1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: index() takes exactly one argument (3 given)

The stub file indicates that 3 arguments can be given. However, removing these extra arguments makes mypy complain about the signature of index being incompatible with supertype Sequence.

You can add a # type: ignore comment to the line mypy is complaining about. It will work.
