Assuming that data is a sequence, each member representing the contents
of a line
(as opposed to the one-big-blob implied about) you can do this:

outp = open("output.txt","w")
outp.write(string.join(data, "\n"))
outp.close()

If you are using Python 2.0 of better you can say:

outp = open("output.txt","w")
for line in data:
	print >> outp, line
outp.close()

Or, if you lack a version <2.0, but not courage, you can:

outp = open("output.txt", "w" )
old_stdout = sys.stdout
sys.stdout = outp
for line in data:
	print line
sys.stdout = old_stdout
outp.close()

Just make sure your other threads don't disagree with your mistreatment
of stdout ...
