How to create a game using Python If and Elif Statements?

Code for creating game with Python using If and Elif statements and Functions:

Rules for this program is:

Computer choose any random value using random.randit function. When it choose 1 it will be equal to ‘s’, 2 = ‘w’ and 3 =’g’. You have to enter ‘s’, ‘w’ or ‘g’ then the program will decide if you win or loose or the match is a tie.

def gameWin(comp, you):
    if comp == you:
        return None
    elif comp == 's':
        if you == 'w':
            return False
        elif comp == 'g':
            return True
    elif comp == 'w':
        if you == 'g':
            return False
        elif comp == 's':
            return True
    elif comp == 'g':
        if you == 's':
            return False
        elif comp == 'w':
            return True

ran = random.randint(1, 3)
if ran == 1:
    comp = 's'
elif ran == 2:
    comp = 'w'
elif ran == 3:
    comp = 'g'

you = input("Your turn: Snake(s) Water(w) or Gun (g)?\n")
a = gameWin(comp, you)

print(f"Computer chose {comp}")
print(f"You chose {you}")
if a == None:
    print("the game is a tie")
elif a:
    print("You win")
else:
    print("You lose")

Output:
