问题描述

Python中的<>运算符到底是什么?为什么据我所知它没有记载?

What exactly is the <> operator in Python, and why is it undocumented (as far as I can tell)?

!=is not相同吗?

推荐答案

Python 2.x <>!=相同(即不等于" ,而不是is not不等于" ),但是后者是首选:

In Python 2.x, <> is the same as != (i.e. "not equal to", rather than is not which is "not identical to"), but the latter is preferred:

比较运算符<>!=是同一运算符的备用拼写. !=是首选拼写; <>过时了.

The comparison operators <> and != are alternate spellings of the same operator. != is the preferred spelling; <> is obsolescent.

在3.x版本中,<> 已被删除,只有存在.

In 3.x, <> has been removed and only != exists.
