A coding tutor is easier to assess when you know the exercise’s answer. Use a short program with one predictable fault, then watch how the tool helps you investigate it.
The exercise
Write a loop that accidentally skips the final item. Ask for a hint rather than corrected code. Does the response lead you to inspect the loop boundary, or replace the entire program before you have understood the issue?
The coding-tutor checklist at easyguides offers a way to organize a comparison. Use the same bug and request with each candidate so you can compare the help, not the difficulty of different exercises.
A useful test log
- What you asked the tutor to withhold.
- The first hint it supplied.
- The test you wrote after reading that hint.
For Python, keep the official Python tutorial nearby when checking language behavior. Generated explanations should be tested against running code and a suitable reference.
Change one condition
Try an empty list, then a list with one item. Explain why the revised loop behaves as expected before asking another question. If you cannot do that yet, request a smaller hint.
End the session by writing the fix in your own words. The useful result is a debugging step you can repeat tomorrow, including a boundary test, rather than a larger pile of code you cannot explain.
A useful follow-up is to recreate the bug in a different tiny program the next day. If you can find the boundary error without the chat, the session has produced a skill you can test independently.
