Several lines of code to call functions in UNIX pipeline Style

After using Linux, you basically know its pipeline, which is to use the output of a program or command as the input of another program or command.

To put it bluntly, let's look at how python can be used to call functions in the Unix pipeline style.

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

The principle is that the decorator + operator is overloaded. (For more information about the decorator, see <the essence of the python decorator>)
Here, the magic method _ ror _ overload operator |
It's really simple and rude. My life is short. I use python!
