What is the purpose of try, except, else, and finally in Python?

Can you explain the purpose of try, except, else, and finally in Python?

Sure! In Python, try and except are used for error handling. The code inside the try block is executed, and if an error occurs, the code in the except block runs.

What about the else block?

The else block runs if the code in the try block executes without any errors. It's useful for code that should only run when no exceptions occur.

And what does the finally block do?

The finally block runs regardless of whether an exception occurred or not. It's typically used for cleanup actions, like closing files.

Can you give me an example of how to use all these blocks together?

Absolutely! Here's a simple example:

try:
    result = 10 / 2
except ZeroDivisionError:
    print('You cannot divide by zero!')
else:
    print('Division successful:', result)
finally:
    print('Execution complete.')
