If you want the script to recieve this line in stdin and write the
output to stdout, you can use the sys.stdin and sys.stdout file
objects. You can also just use "print ..." to write to stdout.
Something like this is simple and readable:

input_line = sys.stdin.readline()
<processing...>
print output_line
