Visual Studio Code – (function) variable: Unbound

I’m writing a program in which the user plays a number guessing game with the computer. The computer chooses it’s number using random. I seem to be running into this error after the user inputs their number. Any idea why? The variable seems to be fine above in the if statement.

import random

player_score = 0
computer_score = 0
restart = 'Y'
stop = 'N'

print("Can you test your luck against the computer?n Guess the number the computer is 
thinking, and you win!")
print("---------------------------------------------------------------------------------------------------------------------------------------")

def game():
player_choice = int(input("Please chose a number: "))
computer_choice = random.randint(0, 5)
if player_choice == computer_choice:
    player_score += 1
    print("You win!nComputer Score: ",computer_score," Player Score: ",player_score)
elif player_choice != computer_choice:
    computer_choice += 1
    print("Computer wins...nComputer Score: ",computer_score," Player Score: ",player_score)

Here’s the terminal window as well.

    as commented by @johnrsharper you need to define global to access variable from inside function:

    import random

player_score = 0
computer_score = 0
restart = 'Y'
stop = 'N'

print("Can you test your luck against the computer?n Guess the number the computer is thinking, and you win!")
print("---------------------------------------------------------------------------------------------------------------------------------------")

def game():
    global player_score
    player_choice = int(input("Please chose a number: "))
    computer_choice = random.randint(0, 5)
    if player_choice == computer_choice:
        player_score += 1
        print("You win!nComputer Score: ",computer_score," Player Score: ",player_score)
    elif player_choice != computer_choice:
        computer_choice += 1
        print("Computer wins...nComputer Score: ",computer_score," Player Score: ",player_score)

    You need to make player_score global.

    import random

player_score = 0
computer_score = 0
restart = 'Y'
stop = 'N'

print("Can you test your luck against the computer?n Guess the number the computer is thinking, and you win!")
print("---------------------------------------------------------------------------------------------------------------------------------------")

def game():
    global player_choice
    player_choice = int(input("Please chose a number: "))
    computer_choice = random.randint(0, 5)
    if player_choice == computer_choice:
        player_score += 1
        print("You win!nComputer Score: ",computer_score," Player Score: ",player_score)
    elif player_choice != computer_choice:
        computer_choice += 1
        print("Computer wins...nComputer Score: ",computer_score," Player Score: ",player_score)
