What are try, except, else, and finally in Python?

Can you explain the try-except-else-finally structure in Python?

Sure! In Python, try-except-else-finally is used for error handling. The 'try' block contains code that might raise an exception.

What happens in the except block?

The except block is executed if an exception occurs in the try block. It allows you to handle the error gracefully.

And what about the else block?

The else block runs if the try block does not raise any exceptions. It's useful for code that should only run when no errors occur.

Finally, what does the finally block do?

The finally block runs regardless of whether an exception occurred or not. It's typically used for cleanup actions.
