How "return" no return ?

`return' always return something (if we except the case of generators).
Used without arguments, it returns None, as you discovered already.
If a function "falls through" its end, None is implicitely returned.

A function always have a value.  I do not understand the need of "not
returning anything".  What do you mean?  What is the real need?

`pass' surely runs.  However, `pass' is not a `return' statement.
