Exception handling is a crucial concept in Python programming, allowing developers to gracefully manage errors and unexpected situations that may arise during program execution. In Python 3, the primary keywords used for exception handling are try, except, else, and finally.

The try block is used to enclose the code that may raise an exception. Within this block, potential exceptions are monitored. If an exception occurs, the control is transferred to the corresponding except block that handles the specific exception type.

The except block catches and manages exceptions. It allows you to define custom actions to take when a specific exception is encountered. You can have multiple except blocks to handle different types of exceptions.

The finally block is always executed, regardless of whether an exception occurs. It is commonly used for cleanup actions, such as closing files or releasing resources, ensuring that essential tasks are completed whether an exception
