Python Exceptions
Overview
In this tutorial, we will explain Python Exceptions in detail. An exception is an unexpected event that occurs during program execution. Errors that occur at runtime are also called exceptions.
Python Exceptions
Python exceptions are runtime errors that occur during the execution of a Python program. An error raises an exception, interrupting the program’s normal flow. It can be caught and handled by appropriate exception-handling mechanisms.
For Example, when we try to divide a number by zero in the program, the following exception ZeroDivisionError is raised. If exceptions are not handled properly, it prints a traceback of that error and details why it occurred.
For Example,
A KeyboardInterrupt exception occurred while running the program. The following trace has been printed because the exception was not handled in the code.
