No you don't.
def f(x):
return x+1
def g(x):
return x-1
If I choose to refactor f() and change "x" to "y", why do I care about
the internal variable inside g()?
Oh wait, I get it... you want to do a global search-and-replace over the
entire file. *face-palm*
If your functions are less than one-screen full, why do you need a global
replacement? Global replacement risks changing words in docstrings,
comments etc that it shouldn't.
