[Tutor] Add newline's, wrap, a long string

[David]

I am getting information from .txt files and posting them in fields on a 
web site. I need to break up single strings so they are around 80 
characters then a new line because when I enter the info to the form on 
the website it has fields and it errors out with such a long string.

here is a sample of the code;

#!/usr/bin/python
import subprocess
import os

u_e = subprocess.Popen(
'grep USE /tmp/comprookie2000/emerge_info.txt |head -n1|cut -d\\"-f2', 
shell=True, stdout=subprocess.PIPE,)
os.waitpid(u_e.pid, 0)
USE = u_e.stdout.read().strip()
L = len(USE)
print L
print USE

L returns 1337

Here is what USE returns;
