Python自学笔记（五）Lambda函数

Lambda函数

简化函数的定义过程

lambda x,y: x+y

使用模块使得小数点不被简化

from _future_ import division

def jia(x,y):

     return x+y

def jian(x,y):

     return x-y

def cheng(x,y):

     return x*y

def chu(x,y):

     return x/y

operator = {"+" : jia , "-" :jian , "*" : cheng , "/" , chu}

def f(x,o,y:

    print operator.get (o) (x,y,*args,**kwargs)

f(3, "+" , 2)
