In Python, exception handling allows you to gracefully handle errors or unexpected situations that might occur during program execution. Let’s dive a little deeper into exception handling with this article.
Error and Exception
Python employs unique objects called exceptions to handle errors that occur during program execution (run time errors/logical errors). When an error occurs that leaves Python confused as to what to do next, it generates an exception and creates an exception object to represent the same.
If you write code to handle the exception, the program will keep executing. If an exception is not handled, the program will halt and display a traceback, including the raised exception. Exceptions are handled using try-except blocks.
A try-except block instructs Python to perform something while also telling it what to do if an exception is thrown. The try … except blocks allow your programs to continue running even if something goes wrong.
If you use exception handling in your programs, then user will see friendly and understandable error messages instead of tracebacks printed by Python which can be confusing to users.
