Review Summary
Excellent work on the Distance class! The implementation correctly handles all the required arithmetic and comparison operations, which is the core of the task.
I am requesting a couple of changes to align your code with the project's checklist requirements.
- Type Annotations: The type hint for the
otherparameter in your magic methods isAny. Please make it more specific, such asDistance | int | float, as required by the type annotation guidelines. - Unnecessary
elseblocks: In methods like__truediv__and the comparison methods, you can remove theelseblock when theifblock contains areturn. The code inside theelsecan simply be unindented.
These changes are important for code clarity and adherence to the project's standards. Once they are made, your solution will be perfect!

This violates the type annotation guidelines in the checklist. The other parameter should have a more specific type than Any, such as Distance | int | float. Please update the type hints for all magic methods to reflect the actual types they support.

This violates checklist item #1 ('Avoid unnecessary else statements'). When an if block contains a return statement, the else block is redundant. You can remove the else and unindent return NotImplemented. This applies to __truediv__ and all comparison methods as well.

Review Summary
Great job on incorporating the feedback from the last review! Your code is looking much cleaner, especially with the removal of the unnecessary else blocks. However, a small but important change is needed before this can be approved. The type annotations for the other parameter in __mul__ and __truediv__ are not quite right. According to the project requirements, these methods should only accept numeric types. Please update the type hint in both methods to be int | float. This will align the code with the checklist requirement that "__truediv__ and __mul__ should not accept a Distance instance as an argument." Once that's fixed, your solution will be perfect. Keep up the great work!

The type annotation for the other parameter isn't quite right here. According to the requirements, this method should only accept numeric types, not another Distance instance.
This violates checklist item #1 under 'Support correct types': "__truediv__ and __mul__ should not accept Distance instance as argument." Please adjust the type hint to int | float.

Similar to __mul__, the type annotation for the other parameter here should only include numeric types.
This violates checklist item #1 under 'Support correct types': "__truediv__ and __mul__ should not accept Distance instance as argument." The type hint should be int | float.

Review Summary
Excellent work on this submission! You've done a great job addressing the previous feedback on type annotations, and your code now correctly meets all the functional requirements. I am approving this solution to help you keep moving forward, but there's a small stylistic improvement I'd like you to consider for future reference.
In your __add__ and __iadd__ methods, you can make the code a bit cleaner and more consistent with your other magic methods. By returning the result directly inside the if and elif blocks, you can remove the final else block. This change would better align with the 'Avoid unnecessary else statements' guideline. This is just a minor point of style, and overall, your logic is solid. Keep up the fantastic work!

This method can be simplified to align with the style of the other magic methods in this class (like __mul__ or __lt__). By returning directly from within the if and elif blocks, you can remove the else block and the final return statement. This change would better follow the 'Avoid unnecessary else statements' guideline from the checklist.

Similar to the __add__ method, this implementation can be refactored for consistency and simplicity. Returning self directly inside the if and elif blocks would allow you to remove the else block and make the code more aligned with the 'Make Code Easier' checklist item.
