From the point of view of the author of a routine, raising an exception is a useful way to signal that a routine could not execute normally-for example, when an input argument is invalid ( e . g . value is outside of the domain of a function ) or when a resource it relies on is unavailable ( like a missing file, a hard disk error, or out-of-memory errors ).
