:It is very important to provide logic in your Python script in case it '''encounters an error'''. An example would be an invalid path-name or trying to close a file that is already closed. The second investigation in this lab will teach you look into how to the Python interpreter '''handle errors''' (commonly referred to as "exception handling") so at run time, and learn how to write Python codes that your Python script will run gracefully even when problems occur during program execution.
