“TypeError: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()

终端显示行pygame.draw.rect(dis,orangecolor[200,150,snake_block, snake_block])的错误代码中是否有错误？我使用visual studio 2019社区版

这是一个打字错误。在orangecolor之后缺少一个,：

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

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