[python-win32] Modify only the first line of a big file (Roughly 1.5MB - For thousands of file).

Hi all, I have thousands of file and I must update only the first line. My concern is : is it possible to read only the first line for each of these files and update the first line only without reading the file completely ? Version of Python is 2.2.1 Thanks for any help, KM

It seems it's not possible if as mentioned you aren't replacing a line with a line of the same lenght/bytes. You then have to resort to using intermediate files see: http://python.pastebin.com/f539b4e46 On Sun, May 3, 2009 at 1:01 PM, Robert kxrobe...@googlemail.com wrote: Khalid Moulfi wrote:
