“类型错误：元组索引必须是整数或切片，而不是元组”是什么意思？

Question

import pygame
import time
import random

# pygame window initialisation
pygame.init()

#declare the colors using their RBG colors
orangecolor = (253, 123, 7)
blackcolor = (0, 0, 0)
redcolor = (213, 50 , 80)
greencolor = (0, 255, 0)
bluecolor = (50, 153, 213)

#Dislay window's width and height
display_width = 600
display_height = 600
dis = pygame.display.set_mode((display_width, display_height))
pygame.display.set_caption("Snake Game")
snake_block = 10
game_over = False
while not game_over:
    for event in pygame.event.get():
        if event.type == quit:
            game_over = True
    pygame.draw.rect(dis,orangecolor[200,150,snake_block, snake_block])
pygame.display.update()
pygame.quit()

the terminal displays an error for the line pygame.draw.rect(dis,orangecolor[200,150,snake_block, snake_block]) is there any error in the code? I use visual studio 2019 community version

Answer 1

It is a typo. There is missing a , after orangecolor :

pygame.draw.rect(dis,orangecolor[200,150,snake_block, snake_block])

pygame.draw.rect(dis, orangecolor, [200, 150, snake_block, snake_block])
