What is the purpose of try-except-else in Python?

The try-except-else block in Python is used for error handling. It allows you to write code that can handle exceptions gracefully.

Can you give me an example of how to use it?

Sure! Here's a simple example:

try:
    result = 10 / 2
except ZeroDivisionError:
    print('You cannot divide by zero!')
else:
    print('The result is:', result)

What happens if there is no exception?

If there is no exception, the code in the else block will execute, allowing you to handle the successful case.

Is it necessary to use else with try-except?

No, using else is optional. You can use try-except without else, but it helps to separate successful execution from error handling.
