In amatchstatement, only one of the options will be executed. Once a match is found, the corresponding block of code runs, and the rest are skipped. Note:Thematch..casestatement was introduced in Python3.10and
Avant Python 3.10, les développeurs Python devaient utiliser plusieurs instructions if-elif-else ou des dictionnaires pour simuler la fonctionnalité de cas de commutation. Voici un exemple de baseutilisant le principe if-elif-else: day=input("Enter the day of the week: ").capitalize()ifday...
参数列表中的Case表达式是一种在编程中常用的条件语句,用于根据不同的条件执行不同的代码块。它通常由一个或多个条件和对应的代码块组成,当满足某个条件时,会执行相应的代码块。 Case表达式可以有多种...

But the detect() function hardly has any code! In fact, all it really does is import the universaldetector module and start using it. But where is universaldetector defined? The answer lies in that odd-looking import statement: from . import universaldetectorTranslated into English, that mean...

Let’s see how we use the switch case in Python using the match case statement in Python. day = input("Enter a number from 1 to 7: ") match day: case "1": print("You selected Sunday") case "2": print("You selected Monday") ...
查看Python官方:PEP 3103-A Switch/Case Statement 发现其实实现Switch Case需要被判断的变量是可哈希的和可比较的,这与Python倡导的灵活性有冲突。在实现上,优化不好做,可能到最后最差的情况汇编出来跟If Else组是一样的。所以Python没有支持。
