Which is probably why I made that mistake. The use of 'raw_input' is 
not that uncommon, but 'input'? I've never seen 'input' being used in 
a real program. It's not very useful anyway, as input("Expression: ") 
seems to do exactly the same as eval(raw_input("Expression: ")). And 
if I'd need a number, I would use float() or int() on whatever 
'raw_input' returns, and probably protect it with a try-except block 
to boot. You can't go far wrong by never trusting user input.
