(python) colour printing with decorator in a function

Question

How can I decorate a function so that anything it prints to stdout is in green and anything it prints to stderr is in red<

Answer 1

This works for me in Bash in my Mac's Terminal.app

import sys
green = '\033[01;32m'
red = '\033[01;31m'

sys.stdout.write(green+"Hello ")
sys.stderr.write(red+"world!")
