* (asterisk) parameter/argument in documentation

[gwynge]

In several areas of documentation such as here https://docs.micropython.org/en/latest/library/machine.Pin.html#machine-pin there is a parameter in a function signature of *. This doesn't seem to be defined and is absent from the list of parameters.

For example: class machine.Pin(id, mode=- 1, pull=- 1, *, value=None, drive=0, alt=- 1)_

What is it?

It means that everything after the * is a keyword-only argument.
