[Tutor] file opening and errors.

I usually use perl but fancy a bit of a change so have started playing
using perl to open a file or directory I usually use:
open(FILE, $file) or die "Error: $!\n";
The $! is a perl variable that holds an error should the open fail,
example being : "No such file or directory".
With python I have use a try except block but I have no idea how I would
get the same warning from python as I would from perl (the reason for
the exception), I am not even sure if this is possible (I assume it must
be) as google searching has been fruitless.
Thanks for any help, pointers and suggestions.
