I guess the easiest for your team would be to:
* let the script write the result lines into a text file
* let the script open the result in an editor (using module called subprocess)
* put a link to your script on the desk

### just an example
# write to file
target  = open("target.txt",'w')
for line in lines:
	target.write(line)
target.close()

# open in editor
import subprocess
subprocess.call(["gedit","target.txt"])
print "*** end ***"
