Python中的Pygame没有响应？

Question

我是Python的新手，我从购买的书中输入了代码来学习它。 我试图制作基本的Skiers pygame，并且每次运行该模块时，pygame窗口都会弹出黑色，然后说“不响应”，我正在使用Windows 8，Python 2.5.7，这是代码。 任何帮助，将不胜感激！

import pygame, sys, random

skier_images = ["skier_down.png", "skier_right1.png", "skier_right2.png", "skier_left2.png", "skier_left1.png"]

        self.image = pygame.image.load("skier_down.png")
        self.rect = self.image.get_rect()
        self.rect.center = [320, 100]
        self.angle = 0

    def turn(self, direction):
        self.angle = self.angle + direction
        if self.angle < -2:  self.angle = -2
        if self.angle >  2:  self.angle =  2
        center = self.rect.center
        self.image = pygame.image.load(skier_images[self.angle])
        self.rect = self.image.get_rect()
        self.rect.center = center
        speed = [self.angle, 6 - abs(self.angle) * 2]
        return speed

    def move(self, speed):
        self.rect.centerx = self.rect.centerx + speed[0]
        if self.rect.centerx < 20:  self.rect.centerx = 20
        if self.rect.centerx > 620: self.rect.centerx = 620

我下载了代码，运行了它，添加了随机图像，这样就不会引发错误，问题似乎就在这里： pygame.sprite.Sprite__init__(self)第31行，您错过了Sprite和__init__之间的点，因此该行应如下所示：

pygame.sprite.Sprite.__init__(self) #added dot
