        else:

        myinput=input(">>>") 
        

，然后我会遇到错误

Traceback (most recent call last):
  File "C:/Users/macla/AppData/Local/Programs/Python/Python310/vom.py", line 8, in <module>
    rooms = pickle.load(f)
AttributeError: Can't get attribute 'Room' on <module '__main__' (built-in)>

吗？

Answer 1

在定义所有课程之前，您正在加载泡菜。 Pickle.load将在Python有机会解析和执行其余类定义之前发生。

通常，您希望避免在模块级别运行任何真实代码；取而代之的是，如果__NAME__ ==“ __ -Main __” block，请在的底部运行这种“主程序”代码。因此：

import ...

class Room: ...

class Object: ...

...

if __name__ == "__main__":
    print("welcome to vom")
    
    with open('test.p', 'rb') as f:
        rooms = pickle.load(f)

    player=Player()

    time.sleep(3.0)

    gorl()
    ...
