Can you explain the try-finally block in Python with an example?

Can you explain the try-finally block in Python with an example?

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

Can you give me a code example?

Absolutely! Here's a simple example:

try:
    file = open('example.txt', 'r')
    # Perform file operations
finally:
    file.close()  # This will execute no matter what

What happens if an error occurs while opening the file?

If an error occurs while opening the file, the code in the finally block will still execute, ensuring that resources are properly released.

Is there a way to handle exceptions in the try block as well?

Yes! You can use an except block along with try-finally to handle exceptions. Here's how:

try:
    file = open('example.txt', 'r')
except IOError:
    print('An error occurred trying to read the file.')
finally:
    file.close()  # This will execute regardless of an error.
