 Background Error checking - anything from checking that the user has
entered a valid respones to a question through to ensuring that
a remote system you need to contact is available - is a vital
part of any program. Sometimes, you can easily check things
with a few if statements, but at other times it's much more
practical to use an exception system where you call for a piece
of code to be run, but then branch off to a particular handler
is a certain condition is triggered.Related technical and longer articles errors v exceptionsTips and short articles on this subject Handling unusual and error conditions - exceptionsWhat are exceptions - Python based answer The case for exceptions Well House Consultants
