This works with lambdas as well, for inline calculations. Here’s a switch statement that assigns to a variable inPHP: switch($value) {case'a':$result=$x*5;break;case'b':$result=$x+7;break;case'c':$result=$x-2;break; } And here’s the equivalent code in Python: result = {'...
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...
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...
Python is a versatile and powerful programming language that offers a multitude of features and functionalities. However, one thing that might surprise newcomers to the language is that Python does not have a built-in switch statement like other popul
但是,在 Python 中,我们看不到 switch-case 或者相近的语法结构,这是为什么呢? 2、Python 为什么不支持 switch? 官方文档中有一篇 FAQ 包含了这个问题:Why isn’t there a switch or case statement in Python? FAQ 即 Frequently Asked Questions 的缩写,表示常见问题,官方列了 27 个常见问题,完整清单在此:...
而python本身没有switch语句,解决方法有以下3种: A.使用dictionary values = { value1: do_some_stuff1, value2: do_some_stuff2, ... valueN: do_some_stuffN, }values.get(var, do_default_stuff)() 具体请参考: Python switch statement 这个方法的缺点是:我不知道do_some_stuff是不是允许多个语句...

While the match-case statement is a powerful tool, its impact on the performance of Python code, particularly in large-scale applications, should be considered. In scenarios with a large number of cases, or complex pattern matching, performance can potentially be impacted. Profiling and testing yo...
