[Tutor] No return statement

[Andre Engels]

My opinion is that one should not create or set a variable if its
value is not used. In the case mentioned, you know what the return
value will be, so there seems to be no reason to keep it.

> For such functions, I assume it's preferred to not catch "None" in a variable.

> Preferred function call:

> 10

> Alternative (where None is caught into z):
> >>> z = printme(10)
> 10
> (And then one could print None)
> >>> print z
> None
