Signature of slice is documented incorrectly #107755
Description
Documentation
https://docs.python.org/3/library/functions.html#slice currently shows:
class slice(start, stop, step=1)
This was changed from slice(start, stop[, step]) in #96579. That default for step is incorrect. It's correct in a range, but in a slice it actually defaults to None:
>>> slice(1,2).step is None
True
Most code handle step=1 and step=None the same way when receiving a slice, but user defined types implementing __getitem__/__setitem__/__delitem__ aren't obliged to, and the correct default should be documented.
