为什么python中没有switch case语句

终于知道了python中映射的设计哲学.

我自己写的code :

 class order_status_switcher(object):

     def get_order_status(self,argument= checkUserAppBookDateResult(appkey,"",1,token)):

         #dispatch method

         method_name = 'number_'+str(argument.get("data").get("orderResultModel").get("orderStatus"))

         # Get the method from 'self'. Default to a lambda.

         method = getattr(self,method_name,lambda :"nothing")

         # Call the method as we return it

         return method()

     # get orderStatus=1,orderStatusDesc="已受理"

     def number_1(self):

         return "已受理"

     #get orderStatus=2,orderStatusDesc="已接单"

     def number_2(self):

         return "已接单"

     #get orderStatus=3,orderStatusDesc="已出发"

     def number_3(self):

         return "已出发"

     #get orderStatus=4,orderStatusDesc="服务中"

     def number_4(self):

         return "服务中"

看完这段代码你就理解了吧.
