Compare these: /* C */ int x = (y != 0) ? 65536/y : 0; # Python x = 65536/y if y else 0 # Python, your way x = [0, 65536/y][y!=0] Do you see where the problem is? Plus, subscripting a literal list is far less readable than the ternary operator. Also: Please can you avoid Google Groups, or if you must use it, please at least clean up the excessive blank lines before you post. I've left them so you can see what we have to cope with. Thanks!
