什么是switch语句?
switch 语句是一种多路分支语句,它将变量的值与 case 语句中指定的值进行比较。
Python 语言没有 switch 语句。
Python使用字典映射在Python中实现Switch Case
例如
function(argument){
switch(argument) {
case 0:
return "This is Case Zero";
case 1:
return " This is Case One";
case 2:
return " This is Case Two ";
default:
return "nothing";
};
};
以上算法的Python语言的实现
例1.Switch Case 语句的实现
def SwitchExample(argument):
switcher = {
0: " This is Case Zero ",
1: " This is Case One ",
2: " This is Case Two ",
}
return switcher.get(argument, "nothing")
if __name__ == "__main__":
argument = 1
print (SwitchExample(argument))
结果
|
1 |
This is Case One |
