That question is ill-defined because Python doesn't have variables.
Python has objects and names. "Change the value of this variable" can
either mean that you want to mutate an object that's passed by the
caller, which you can do as long as the object is mutable, or you want
to rebind a name in the caller's namespace, which you can't do.

Why do you think your function needs to have side-effects instead of
simply returning a return value?
