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

[vince spicer]

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)
