python switch 替换if else

1,python 解释器版本3.10以上可以使用如下

def dar(darling):
    match darling:
        case '400':
            print(400)
        case '401':
            print(401)
        case _:
            print(404)


if __name__ == '__main__':
    dar('400')

解释器版本，小于3.10 会报错SyntaxError: invalid syntax

2,所有版本

status = {
    '400': lambda: stat400('400'),
    '401': lambda: stat401(),
    '404': lambda: print('我是404')

}

def stat400(x):
    print('我是400' + x)

def stat401():
    print('我是401')

if __name__ == '__main__':
    status.get('404', lambda: print('未找到'))()
