Should this not be

	if not open( disk ):
	    error( "Can't open disk" )
	else:
		do_lots_of_things_with(disk)

as for readability ?

Or even

	if not open( disk ):
	    error( "Can't open disk" )
	    return what_needs_to_be_returned

	do_lots_of_things_with(disk)

The latter version may need some code reorganization, though.
