语法糖 - Python pipe管道用法

Question

Python语法问题

描述

我使用第三方的pipe管道库，来进行一些类似linux sh中管道方式运算，遇到疑惑。见如下代码：

>>> from pipe import *
>>> [1, 2, 3] | sum
>>> 6

上面这段代码，管道描述符| 在python中不是按位或的运算符吗，为这么在这里可以作为类似linux下的管道符呢？查看pipe.py源文件，没有发现重载这个运算符啊？

Answer 1

Found it, carefully looked at the pipe.py file, and found that the class Pipe has re-added the bitwise OR operator, realizing a function similar to the pipe operator in Linux sh.

Summary

1. Like the scapy library, the / division operator is overloaded and used as a connection operator, so pay special attention to this type of operator overloading in the future.
