几行代码实现unix管道风格的函数调用

废话少说,下面我们看用python怎么实现unix管道风格的函数调用.

#coding=utf-8
class Pipe:
    def __init__(self, func):
        self.func = func

    def __ror__(self, other):
        return self.func(other)

@Pipe
def add(args):
    return sum(args)

@Pipe
def incr(arg):
    return arg + 1

print [1, 2, 3] | add | incr
