调试一个简单的pygame游戏

Question

当我运行这个时，它会执行一个导入错误。我在代码的结尾处发布了错误。该程序本质上不运行，我不知道回溯发生了什么错误。任何洞察力将不胜感激。

from livewires import games, color

不知道livewires什么，但下面看起来可疑：

le_chef = Chef =() 
games.screen.add(le_chef) 
le_pan = Pan =() 
games.screen.add (le_pan) 

你上课叫厨师，潘，但你不会对这些做任何事情 - 只需将这些东西分配给一个空元组，然后将它们添加到games.screen。他们是否应该初始化？

例如。

le_chef = Chef(<some args>) 
le_pan = Pan(<some args>)
