Generating and consuming infinite unix pipes with Python

consumer.py

#!/usr/bin/env python
import fileinput
import sys

# Reverse each incoming line
input_lines = fileinput.input(sys.argv[2:])
for line in input_lines:
    line = line.strip()[::-1] + '\n'
    sys.stdout.write(line)

factory.py

#!/usr/bin/env python
from sys import stdout
from time import sleep

# Print an integer roughly once every second
i = 0
while(True):
    stdout.write(str(i) + '\n')
    i += 1
    sleep(1)

forever.sh

#!/bin/bash
stdbuf -o0 python factory.py | python consumer.py -

# Depending on your system, you may instead need this:
#unbuffer python factory.py | python consumer.py -
