Because it's a bad idea to do so and Python doesn't encourage such sloppy 
behaviour. If you like it, though, you might prefer PHP.

By the way: error reporting is definitely *not* hand-holding. It is 
simply not good to let errors pass silently by default. Again, if you 
think the contrary, PHP is your friend ;-)
