推荐答案

您已经在Python中找到了一个复活节彩蛋.这是个玩笑.

You have found an easter egg in Python. It is a joke.

这意味着将永远无法使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__模块导入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.

所以行from __future__ import braces表示您想启用用括号创建块"功能，该异常告诉您永远发生的可能性为零.

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中包含的一连串笑话中，就像import __hello__，import this和import antigravity一样. Python开发人员具有良好的幽默感！

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!
