Can you give us some idea of your skill level, and perhaps some code
that you've already tried?
Your general approach will be something like

open read_file
open write_file
read read_file into a list
close read_file
iterate over the list
    if you find a line you want to change
        make the change and write to write_file
    else
        write to write_file

close write_file

HTH,
