What is the purpose of 'else' in a 'try-except' block?

The purpose of 'else' in a 'try-except' block is to execute a block of code only if the 'try' block does not raise an exception. When you use 'else', it allows you to define code that should run only when the operations in the 'try' block are successful and exception-free.

In a typical usage scenario, you perform your main operations within the 'try' block. If everything runs smoothly and no exceptions occur, the code within the 'else' block will execute. This is particularly useful for handling follow-up actions or post-processing that you only want to happen when the initial code runs without any issues.

Choosing this option reflects an understanding of structured exception handling, which is common in scripting and programming. The 'else' structure provides clarity and separation of logic, ensuring that specific actions are contingent upon the success of the preceding code.
