files: direct access - NOT sequential

[Patrick Carabin]

Terry,
""" open in 'w' mode or (probably better for Windows,  'wb') mode and 
use tell() and seek() methods. """

Thank You.

i found tell() and seek() as properties/mrthods of the ( opened ) 
file object...

But i still have a problem : open in 'w' mode  ( or 'wb' : what can 
be the difference? ) does ERASE the contents of the file, so 
everything is lost ...

1 more question :
how do i have to manage it to keep the contents that are already in 
the file ? Do You have some example?

TIA

Patrick Carabin.
