13# Global Variables
14player_strength = 2
15def increase_strength():
16	player_strength = 3		# this will give you an error because the player_strength
17    # is defined in the global scope so you can't modify it in a function
18    
19    # if you try to print the global variable in function you can do it
20    print(player_strength)
21    
22# Local
23	# only accessed/edited by the functions only
24# Global
25	# accessed/edited in global level not in functions
26    # only accessed by functions but not editable

3only inside the function. These variables
4are not used or referred by any other function.
