global python function code example

Example 1: global variable not working python

trying to assign a global variable in a function will result in the function creating a new variable
with that name even if theres a global one. ensure to declare a as global in the function before any
assignment.

a = 7
def setA(value):
    global a   # declare a to be a global
    a = value  # this sets the global value of a
