It means to return None.

If it's the last statement in the function, you don't need it.
Some people do it just as a formal indicate that that's the end
of the function.

OTOH, sometimes people want to return explicitly from somewhere
within the function:

def foo(x):
    if x<0:
        return
    else:
        whatever
