} 但是在Python中,官方对switch case的需求是这样回复的: " You can do this easily enough with a sequence of if... elif... elif... else. There have been some proposals for switch statement syntax, but there is no consensus (yet) on whether and how to do range tests. " 感觉有点low。
不过，之所以会出现这种情况，也许跟他的预设立场有关：他似乎认为“Python is fine without a switch statement”，因此尽管写了很长的 PEP，但只是在把问题复杂化，把议题搁置起来。最后，他在 PyCon 上做了一个小范围调查，借此“名正言顺”地拒绝了自己发起的 PEP，试图堵住众人的悠悠之口……4、未来会有 s...

大多数语言都提供了 switch 语句或者极其相似的东西,例如,在 C/C++/Java /Go 等静态语言中,它们都支持switch-case结构;在 Ruby 中有类似的 case-when 结构,在 Shell 语言中,有相似的 case-in 结构,在 Perl 中,有 switch-case-else…… switch 语句的好处是支持“单条件多分支”的选择结构,相比 if-else ...

The Python programming language does not have a built in switch/case control structure as found in many other high level programming languages. It is thought by some that this is a deficiency in the language, and the control structure should be added. This paper demonstrates that not only is...
