！=和<>有什么区别? [英] What is the difference between != and <>?

问题描述

也许这是一个相当新手的问题，但我很好奇.我已经尝试过搜索，但是我想我缺少正确搜索的正确术语.

Perhaps this is a rather newbie-ish question, but I'm curious. I have tried searching for it, but I suppose I lack the correct terminology to search properly.

!=和<>之间的差异.

在再次搜索不平等"时，我发现其中一个讨论了not ==和!=，但没有讨论<>.

On searching again, "inequality", I found one that discusses not == and !=, but nothing about <>.

推荐答案

在Python 2.x中，<>等效于!=，如

In Python 2.x, <> is equivalent to !=, as described in the documentation:

<>和！=的形式是等效的；为了与C保持一致，最好使用！=；其中下面提到的！=也被接受<>. <>拼写被认为是过时的.

The forms <> and != are equivalent; for consistency with C, != is preferred; where != is mentioned below <> is also accepted. The <> spelling is considered obsolescent.

在Python 3.x中，<>已被删除.再次，文档说:

In Python 3.x, <> has been removed. Again, the documentation says:

已删除语法

....

已删除<>(改用！=).

Removed <> (use != instead).
