"return" in def

[Roger]

Hi Everyone,

First I want to thank everyone that posts to this group.  I read it
daily and always learn something new even if I never feel like I have
anything to contribute but my questions.

When I define a method I always include a return statement out of
habit even if I don't return anything explicitly:

def something():
        # do something
        return

Is this pythonic or excessive?  Is this an unnecessary affectation
that only adds clock ticks to my app and would I be better off
removing "returns" where nothing is returned or is it common practice
to have returns.

Even when I'm not explicitly returning something I like to add
"return" because it's a good additional visual marker for me to see
where a method definition ends especially in cases where I may use a
nested method.

Thanks for the discussion!
Roger.
