What is the difference between finally and else in Python?

What is the difference between finally and else in Python?

In Python, 'finally' is used in try-except blocks to ensure that certain code runs regardless of whether an exception occurred, while 'else' is used after 'try' to execute code if no exceptions were raised.

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

Sure! Here's an example:

try:
    x = 1 / 1
except ZeroDivisionError:
    print('Division by zero!')
else:
    print('No exceptions, x is:', x)
finally:
    print('This will always execute.')

What happens if I don't use finally?

If you don't use 'finally', any cleanup code you intended to run may not execute if an exception occurs, potentially leading to resource leaks.

Are there any performance implications of using finally?

Using 'finally' does have a slight overhead, but it's generally negligible compared to the benefits of ensuring code execution for cleanup.
