Using Python if statement in Cases In Python, we can also use theifstatement in the case clauses. This is calledguard, which adds an additional condition to an expression. If the guard condition (theifstatement) evaluates toFalse, thematchstatement skips that case and continues to the next ...
case ["exit"]: print("退出程序") case _: print("无效的命令") 在这个项目中,match语句根据用户输入的命令进行模式匹配,执行相应的操作。如果用户输入 “open test.txt”,会匹配到case ["open", file_name]子句,输出 “正在打开文件 test.txt”。 游戏角色状态处理 classCharacter: def__init__(self, ...
Python3.10.0正式版本在月初终于发布了,其中一个重要的特性就是支持match-case语句,这一类似C语言switch-case语句终于在Python中实现了。 一般匹配模式 C语言中一个典型的swicht-case语句像下面这样,在switch里包含要判断的变量x,case语句后则是匹配变量值是多少,如果满足这个匹配条件,就执行“case n:”后面的语句,...

A match statement takes an expression and compares its value to successive patterns given as one or more case blocks. This is superficially similar to a switch statement in C, Java or JavaScript (and many other languages), but it can also extract components (sequence elements or...
