I would do:
i = int(input.readline())
immediately followed by:
Otherwise you would just read one byte, which exhosts
after 256 accesses.
This, however, is probably not related to your problem.
Also, the file must initially contain a valid integer.

I would guess you do have read permissions on the directory
containing the file but not write permissions. As said, just
a guess. (user "you" might be different if running from command
