推荐答案
您在 Python 中发现了一个彩蛋.开个玩笑.
You have found an easter egg in Python. It is a joke.
这意味着永远不会实现用大括号而不是缩进来分隔块.
It means that delimiting blocks by braces instead of indentation will never be implemented.
通常，从特殊__future__ 模块 启用向后不兼容的功能，例如 print() 函数或真正的除法.
Normally, imports from the special __future__ module enable features that are backwards-incompatible, such as the print() function, or true division.
因此，from __future__ import braces 行表示您要启用使用大括号创建块"功能，并且异常告诉您永远 发生的都是零.
So the line from __future__ import braces is taken to mean you want to enable the 'create blocks with braces' feature, and the exception tells you your chances of that ever happening are nil.
您可以将其添加到 Python 中包含的长长的笑话列表中，就像 import __hello__、import this 和 import antigravity.Python 开发者的幽默感很强！
You can add that to the long list of in-jokes included in Python, just like import __hello__, import this and import antigravity. The Python developers have a well-developed sense of humour!
