Python不导入数据结构

我正在尝试创建一个基于文本的游戏。我已经做了一个基本/通用的介绍，现在它越来越长，所以我想创建一个新文件，以便我可以添加诸如盔甲和武器之类的东西。当我尝试导入'my_character'时，它给了我一个错误，所以我去研究这个问题，我发现了这个，所以我试了一下。我刚刚收到一条错误消息，说它没有定义（类似于下面的错误）。这是名为intro的介绍部分：

我在part1上输入的命令是尝试导入 my_character 是：

from intro import my_character
print(my_character)

我一直在尝试导入，my_character但结果是：

Traceback (most recent call last):
  File "C:/Users/user/Desktop/part1.py", line 5, in <module>
    my_character
NameError: name 'my_character' is not defined

原始文件名为“intro”，新文件名为“part1”。我需要做'if name == "__main "' 的事情吗？如果是这样，那有什么作用？
