I guess it depends on the language. Exceptions are a normal way of
working in Python. For example, in many languages you rely on
returned codes from functions to determine if they completed
successfully. In Python, the normal thing to do is have the function
raise an exception, and then handle that exception in the calling
program.
When it is designed to work this way, it isn't really "error
handling"; it's just a routine programming idiom.
