If it's the last statement in the function body, it is indeed "excessive".

OTHO I sometimes end a function with an explicit "return None" when 
there are branches with early returns, ie:

def func():
    if some_condition:
        return something
    return None

to make really clear what happens - even if it _should_ be clear without 
the last statement.  IOW : use your own judgement.
