So *you* need to add the newlines, e.g. you can use a list comprehension:
fob.writelines(["%s\n" % (x) for x in users])
or write in a loop:
for u in users:
fob.write("%s\n" % (u))
or join the list elements together with a newline separator (but you'll
need to add a final newline by hand):
fob.writelines("\n".join(users) + "\n")
