What are try, except, else, and finally in Python?

Can you explain how try, except, else, and finally work in Python?

Sure! In Python, try-except blocks 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 and finally parts?

The else block runs if the try block executes without any errors. The finally block runs regardless of whether an error occurred or not, often used for cleanup actions.

Can you give me an example of how to use all four?

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.')

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

If there's an error in the else block, it will not be caught by the try-except structure, and the program will terminate unless you have another try-except around it.
