What is the purpose of try-finally in Python?

Can you explain the purpose of try-finally in Python?

Sure! The try-finally block is used to ensure that certain cleanup actions are taken, regardless of whether an error occurs.

Can you give me an example of how to use try-finally?

Of course! Here's a simple example:

try:
    file = open('example.txt', 'r')
    # Perform file operations
finally:
    file.close()  # This will always execute, even if an error occurs.

What happens if there's an error in the try block?

If an error occurs in the try block, the code in the finally block will still execute, ensuring that resources are cleaned up.

Is try-finally the same as try-except?

Not exactly. try-except is used to handle exceptions, while try-finally is used for cleanup actions, regardless of exceptions.
