python中switch语句用法
python中是没用switch语句的,这应该是体现python大道至简的思想,python中一般多用字典来代替switch来实现。
#coding: utf-8 from __future__ import division def jia(x,y): print x+y def jian(x,y): print x-y def cheng(x,y): print x*y def chu(x,y): print x/y operator = {'+':jia,'-':jian,'*':cheng,'/':chu} def f(x,o,y): operator.get(o)(x,y) f(3,'+',2)
上面的代码就用字典实现了选择功能,要是在C++中实现上述功能,是用switch实现的,但是用python的字典实现起来更简单
