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...
在编程中,case表达式是一种条件语句,用于根据不同的条件执行不同的代码块。舍入是一种数学运算,用于将一个数值按照一定的规则进行近似取整。 在case表达式中的舍入,通常指的是在条件判断中对浮点数进...
"# Since Pierre's suggestion is backward-compatible with the original recipe,# I have made the necessary modification to allow for the above usage. 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...
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") ...

说明:在以上示例中,如果选项为1,则计算圆柱体的表面积;如果选项为2,则计算圆柱体表面积,最后选择选项3,计算圆柱体的体积。 使用类切换案例语句以将文字转换为字符串“month” classPythonSwitchStatement: defswitch(self,month): default="Invalidmonth"

Python本着“简单”的设计原则,控制语句只有判断流程if...else...和循环语句while/for,并没有类似于C语⾔的switch语句。 这样,带来的问题是遇到多条件判断时只能使⽤if判断语句,导致⼀⼤堆的if语句,代码丑陋不美观。 if i == 1: statement elif i == 2: statement ... ... ... else: statement...
