What is the for-else statement used for?

• A. To execute code once the for loop is done.
• B. To repeat the for loop indefinitely.
• C. To skip the iteration in a for loop.
• D. To check for conditions within the for loop.

Answer: (A)

The for-else statement in Python is used to define a block of code that will execute after the for loop completes its iterations. This feature is particularly useful when you need to run a specific piece of code after all iterations have taken place, provided that the loop didn't encounter a break statement. If a break is present, the else block will be skipped. Utilizing the for-else structure can help in scenarios where you want to confirm that a loop completed its iteration over all required items without interruption. The completion of the loop can indicate that all conditions or searches were processed, providing a clear logical flow in your program. Other options either describe intentions that do not align with Python's functionality or suggest uses that aren't defined within the for-else construct. For example, the ability to repeat the loop indefinitely does not apply because a for loop is designed to iterate over a defined range or collection. Similarly, skipping iterations or checking conditions occurs within the loop body itself, not as a feature related to the for-else statement.
