关于python的问题，请各位解答！急！

用Pycharm的"AttributeError: 'str' object has no attribute 'convert_alpha'"如何解决，急！
请看看如何解决？

谢谢！

你的代码中，错误出现在这行:

frame = pygame.image.load(os.path.join("pictures\\Style_1_male_walking.gif").convert_alpha())

问题是 convert_alpha() 是 pygame.Surface 类的方法，也就是图片加载后(pygame.image.load)才可以调用。但你试图在字符串上使用这个方法，这就是为什么你收到 'str' object has no attribute 'convert_alpha' 错误。

你应该首先调用 pygame.image.load() 来加载图片，然后在结果上调用 convert_alpha()。

这样修复你的代码:

frame = pygame.image.load(os.path.join("pictures", "Style_1_male_walking.gif"))
frame = frame.convert_alpha()
frames.append(frame)

注意我也在 os.path.join 中使用了逗号来分隔目录和文件名，这是它的正确使用方法。os.path.join 会根据你的操作系统自动选择正确的路径分隔符。

第46行代码错误
代码应修改为

frame = pygame.image.load(os.path.join("pictures\\Style_1_male_walking.gif")).convert_alpha()
