How do I use try-finally in Python?

The try-finally statement in Python is used to ensure that certain cleanup actions are performed, regardless of whether an error occurs. Would you like an example?

Yes, please provide an example.

Sure! Here's a simple example:

try:
    file = open('example.txt', 'r')
    data = file.read()
finally:
    file.close()

In this case, the file will be closed whether or not an error occurs while reading it.

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. This is useful for cleanup actions like closing files or releasing resources.
