Can you elaborate please?

There is a better technique, not requiring 'global' ,
which even Guido dislikes: use a module level class instance,
and assign to an attribute of it: one level of indirection defeats the
localisation:
class X(): pass
x = X()
def f(y):
x.y =1 # assign to attribute of global instance
