first, grabbing output from an external command try:
import commands
USE = commands.getoutput('grep USE /tmp/comprookie2000/emege_info.txt
|head -n1|cut -d\\"-f2')
then you can wrap strings,
import textwrap
Lines = textwrap.wrap(USE, 80) # return a list
so in short:
import commands, textwrap
data = textwrap.wrap(commands.getoutput('my command'), 80)

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;

Thanks Vince,
I could not get command to work, but I did not try very hard;
["cut: the delimiter must be a single character Try `cut --help' for
more", 'information. head: write error: Broken pipe']
But textwrap did the trick, here is what I came up with;
#!/usr/bin/python
import subprocess
import os
import textwrap
import string
def subopen():
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 = textwrap.wrap(USE, 80) # return a list
Lines = string.join(L, '\n')
fname = 'usetest.txt'
fobj = open(fname, 'w')
fobj.write(Lines)
fobj.close
subopen()
Here is the output;
