too many values to unpack (expected 3) pygame click issue

I am currently working on a CS50 project studying the AI required for tic-tac-toe. however I can't get the runner.py file to run, as I get the following error:

Traceback (most recent call last): File "/Users/newtracksuit/Downloads/tictactoe/runner.py", line 57, in click, _, _ = pygame.mouse.get_pressed() ValueError: too many values to unpack (expected 3)

here is the full code provided, I have yet to write any actual functionality to the tic-tac-toe program, Just need to understand why this is not working yet

import pygame
import sys
import time
