You might be able to use "edge" case to make this simple. 1) If the line you are replacing is unique in the file
and 2) File can easily fit in memory you can write: fp=open(filename, 'r') contents=fp.read() fp.close() newcontents=newline.join(contents.split(line2)) fp=open(filename, 'w') fp.write(newcontents) fp.close() For small files this is very efficient.
