python中reduce用法，pythonreduce用法,>>> def myfu

>>> def myfunction(a,b):...     return a*b...>>> mylist = [1,2,3,4,5]>>> print reduce(myfunction, mylist)120#上面的代码相当于：>>>print ((((1*2)*3)*4)*5)120#也可以直接使用操作符模块来替代函数>>> import operator>>> mylist = [1,2,3,4,5]>>> print reduce(operator.mul, mylist)120>>> print reduce(operator.add, mylist)15
