In the first example the code outputs 1. In the second example I get the error code: Local Variable 'x' referenced before assignment. Can anyone explain the reasoning for this?
Example 1:
def num():
global x
x = 1
def test():
print(x)
num()
test()
Exmaple 2:
def num():
global x
x = 1
def test():
while x < 10:
print(x)
x+=1
num()
test()
