Can you clarify a bit? I'm not sure why do you need to define any
additional variables at all. You do not return variables
from a function - you can return *a value* which may be
a simple type or complex type.

Or maybe you mean something like creating a global name
from inside of a function? Well, that doesn't sound like a good idea,
though...

>>> def foo():
	global a
	a = 5
	
>>> foo()
>>> print("The variable is: ", a)
The variable is:  5
>>>
