That may be true but you will make your code much less reusable
and much more error propne in the process. There are good reasons
why global variables are considered evil...

I'm not sure how you work that out. If the function uis getting bad
data
it will still return it regardless of whether you use golobals or
return values.

just use the global keyword:
###############
x,y = 42,27
def f():
global x,y
x = 66
y = 42
print x+y
print x,y
f()
print x,y
############
But its very bad practice and
##############
x,y = 42,27
def f(x,y):
x = 66
y = 42
print x+y
return x,y
print x,y
x,y = f(x,y)
print x,y
##########
is much better.
