What arguments does Python sort() function have?

Question

Is there any other argument than key, for example: value?

Answer 1

Yes, it takes other arguments, but no value.

>>> print list.sort.__doc__
L.sort(cmp=None, key=None, reverse=False) -- stable sort *IN PLACE*;
cmp(x, y) -> -1, 0, 1

What would a value argument even mean?
