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)
