    I thought seek was only to find the beginning and/or end of a file?

      seek will allow you to position the file pointer to any offset within the file. The problem is that files are ordered sequences of octets, not lines. Unless you're dealing with fixed line lengths you're more than likely going to overwrite something if you try and do things in place yourself. You want to use the module mentioned in the FAQ I've referenced.
