else and finally

Keep the success path in else, put guaranteed cleanup in finally, and know the exact order in which the clauses run.

You will be able to

• Use else for code that should run only when the try block succeeded
• Use finally for cleanup that must happen whether or not an exception occurred
• Predict the order of try, except, else and finally, including with return
• Keep try blocks small so that except clauses catch only the failures they are meant for
