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

# Python global variable
# Probably should not use this, just pass in arguments
x = 0 # variable is in outer scope
print(x) # prints x (0)

# if using a global variable, the variable will not need to be mention while calling the function
global x # calling the x variable from a function
x += 1
