global python

"""
USING GLOBALS ARE A BAD IDEA, THE BEST WAY TO PERFORM AN ACTION WHICH NEEDS GLOBALS WOULD 
BE TO USE RETURN STATEMENTS. GLOBALS SHOULD ONLY EVER BE USED IN RARE OCCASIONS WHEN YOU
NEED THEM

def test_function():
  global x
  x = 10

test_function()
print(f"x is equal to {x}") # returns x is equal to 10
