Python Tutorial for Beginners 37 - Try Except Else Finally (Python Excep...

In this Python Tutorial for Beginners video I am going to show How to use Try Except Else Finally in Exception handling in Python.
else: statements executed if no exception
finally:clean-up statements always executed
A finally clause is always executed before leaving the try statement. A finally statements is guaranteed to be executed before leaving the try statement, whether an exception has occurred or not.
What are these exceptions? An exception is an event, which happens while the execution of a program, that disrupts the normal flow of the program. When some error error occurs an exception is raised. Python Exceptions are run-time errors. Exceptions are used to deal with extraordinary errors. Normally if we do not use Exception handling the execution of program stops as soon as exception is thrown.By default, the interpreter handles exceptions by stopping the program and printing an error message.
