Aside:
Normally you would use the help() function to find out
how methods work and what they return but sadly the
documentation for the in-place methods doesn't indicate
the return is None. Some of them have a warning that
its "IN PLACE" but remove does not. Which is a pity.
>>> help([].sort)
Help on built-in function sort:
sort(...)
L.sort(cmp=None, key=None, reverse=False) -- stable sort *IN PLACE*;
cmp(x, y) -> -1, 0, 1
(END)
>>> help([].remove)
Help on built-in function remove:
remove(...)
L.remove(value) -- remove first occurrence of value.
Raises ValueError if the value is not present.
(END)
Personally I think it would help if the first lines
for these methods read like:
remove(...) -> None
L.remove...etc
Are you using Python 2? Because this is what I get in Python 3:
remove(...)
L.remove(value) -> None -- remove first occurrence of value.
Raises ValueError if the value is not present.
The same for help(list.sort) BTW.
