我没事写了个代码，一运行就一直报错
代码如下
# -*- coding:utf-8 -*-
import pygame as p
import sys as s
result = input("Welcome!If you want to play the game,please enter 1,if you want to know the writer,please enter 2 ,if you want to exit,please enter 3,if you want to experience other functions,please enter 4")
if result == 1:
def game():
p.init()
size = width,height = 500,400
screen = p.display.set_mode(size)
color = (0,0,0)
ball = p.image.load("ball(1).jpg")
ballrect = ball.get_rect()
speed = [5,5]
clock = p.time.Clock()
while True:
clock.tick(60)
for event in p.event.get():
if event.type == p.QUIT:
s.exit()
ballrect = ballrect.move(speed)
if ballrect.left < 0 or ballrect.right > width:
speed[0] = -speed[0]
if ballrect.top < 0 or ballrect.bottom > height:
speed[1] = -speed[1]
screen.fill(color)
screen.blit(ball,ballrect)
p.display.flip()
p.quit()
game()
if result == 2:
print("Writer:ekl All Rights Reserved.")
if result == 3:
exit()
else:
result = input("the functions are developmenting and they're dangerous,Sure to use it?(Yes or No)")
if result == "Yes": #有问题
result = input("Plase choose the experiences 1.command 2.games 3.exit 4..........（only enter the numbers)")
if result == 1:
print("please write the command")
result = input("e.g:exit()")
if result == "exit()":
exit()
if result == "game()":
game()
else:
print("the command is wrong,the program will exit")
exit()
if result == 2:
pass
if result == 3:
exit()
