New submission from Dan Snider <[email protected]>:
Unfortunately, it looks like there's no requirement for an abc.Sequence to
implement the 3 argument form of seq.index, so I suppose this is technically
just a documentation bug...
>>> range(5).index(2, 1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: index() takes exactly one argument (2 given)
>>> help(range.index)
Help on method_descriptor:
index(...)
rangeobject.index(value, [start, [stop]]) -> integer -- return index of
value.
Raise ValueError if the value is not present.
