My apologies for asking a trivial question about programming practice.
As mentioned in the online tutorial
functions which lack a return statement ('procedures') actually return "None".
For such functions, I assume it's preferred to not catch "None" in a variable.
>>> def printme(x):
Preferred function call:
Alternative (where None is caught into z):
>>> z = printme(10)
(And then one could print None)
>>> print z
