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。 解...
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...
In Python, switch-case statements don’t exist because of unsatisfactory proposals. Many proposals failed as they could not work well with Python’s syntax and established coding style. Most programming languages provide switch case functions because they lack proper mapping constructs, and the reason...
python原生没有switch case的语法 使用下面的方案可以替代 代码语言:txt AI代码解释 # Function to convert number into string # Switcher is dictionary data type here def numbers_to_strings(argument): switcher = { 0: "zero", 1: "one", 2: "two", } # get() method of dictionary data type re...

一般而言,switch 的语法格式如下: switch(expression){ case value1: // 语句 break; // 可选 case value2: // 语句 break; // 可选 default: // 可选 // 语句 } 使用流程图来表示,大概是这样的: 它的用法不难理解:switch 语句的值满足哪一个 case 情况,就会执行对应的代码块,执行时遇到 break 就...
