Python不等于运算符 [英] Python not equal operator

问题描述

我来自ac风格语言，因此我很自然地使用！= 来表示不相等，但是当我使用Python时，从阅读的文档中我学到了为此使用了<> 运算符。

I come from a c style languages, so I am natural in using != as not equal, but when I came to Python, from the documentation I read, I learned that for this purpose the <> operator is used.

最近，我已经看到很多使用！= 的代码，所以我的问题是是否其中之一是

Recently, I have seen a lot of code using !=, so my question is if one of them is preferred over the other or is one of them deprecated.

此外，我想知道它们之间是否有任何区别。

Also, I would like to know if there is any difference between them.

推荐答案

Python 2支持两者，在python 3中，<> 运算符

Python 2 supports both, in python 3 the <> operator has been removed.

两者之间没有区别，但是 ！= 是首选形式。

There is no difference between the two, but != is the preferred form.
