I've also tried moving "MyVar = 7" to the first line, but that doesn't
change anything. Using "global MyVar" works..
Try
def outer():
MyVar = 10
def Proc1():
nonlocal MyVar
MyVar = 5
Proc1()
MyVar = 7
outer()
print(MyVar)
From the documentation
The nonlocal statement causes the listed identifiers to refer to
previously bound variables in the nearest ******enclosing scope
excluding globals******. This is important because the default behavior
for binding is to search the local namespace first. The statement allows
encapsulated code to rebind variables outside of the local scope besides
the global (module) scope.
Names listed in a nonlocal statement, unlike those listed in a global
statement, must refer to pre-existing bindings in an enclosing scope
(the scope in which a new binding should be created cannot be determined
unambiguously).
Names listed in a nonlocal statement must not collide with pre-existing
bindings in the local scope.
