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

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

Sure! The try-except-finally structure is used for error handling in Python. It allows you to write code that can handle exceptions gracefully.

What happens if an exception occurs in the try block?

If an exception occurs in the try block, the code in the except block will be executed to handle the error.

And what is the purpose of the finally block?

The finally block is executed no matter what, whether an exception occurred or not. It's typically used for cleanup actions.

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

Certainly! Here's a simple example:

try:
    x = 1 / 0  # This will raise a ZeroDivisionError
except ZeroDivisionError:
    print('You cannot divide by zero!')
finally:
    print('This will always execute.')
