But how do you know what exceptions could be raised?

I love Python in a big way, but this is one thing Java has on Python -
knowing what exceptions are relevant.

Python's approach is great as long as an uncaught exception should cause
termination of the program - and most of my programs fit into this
category.  But not all of them.
