Elegant Python-A few lines of code to implement UNIX pipe-style function calls

Using Linux's basic knowledge of its pipeline is to use the output of a program or command as an input to a program or command.

Less nonsense, let's look at how Python implements the UNIX pipeline style function call.

#coding =utf-8class Pipe:    def __init__ (Self, func):        Self.func = func-    def __ror__ (self, Other):        return Self.func (Other) @Pipedef Add (args):    return sum (args) @Pipedef incr (ARG):    return arg + 1print [1, 2, 3] | add | incr

The principle is the adorner + operator overload. (See the essence of the <python decorator for the adorner smattering >)
Among the magic methods __ror__ overloaded Operators |
It's so simple and rough. Life is short, I use python!
