What is the difference between try-except and try-finally?

Can you explain the difference between try-except and try-finally in Python?

Sure! The try-except block is used to catch and handle exceptions, while try-finally ensures that a block of code runs regardless of whether an exception occurred.

Can you give me an example of each?

Of course! In a try-except, you might handle a division by zero error. In try-finally, you could ensure that a file is closed after opening it, regardless of errors.

What happens if both are used together?

If you use both, the try-except can catch exceptions, and the finally block will execute after the try-except, ensuring cleanup.

Are there any performance differences between them?

Generally, try-except can be slightly slower due to the overhead of exception handling, but the difference is usually negligible.
