Review Summary

I am approving your solution because it fully meets the functional requirements and all core behaviors work correctly for initialization, string/repr output, arithmetic operations, and comparisons. Your Distance class correctly handles both Distance and numeric inputs where required, and respects the constraint that __mul__ and __truediv__ only accept numbers, with division rounded to two decimals. The only issue noted is a minor style point in app/main.py within __iadd__, where you use an else after an if that already determines the return path; this relates to the guideline to avoid unnecessary else blocks after an early return. For example, instead of:

if isinstance(other, Distance):
    self.km += other.km
else:
    self.km += other
return self

you could write:

if isinstance(other, Distance):
    self.km += other.km
    return self
self.km += other
return self

This is a stylistic improvement rather than a functional problem, so it does not block approval; overall, you’ve implemented the class cleanly and aligned well with the task requirements.

This violates checklist item #1: "Avoid unnecessary else statements". After handling the Distance case, you can return directly and then fall through to self.km += other without using else.

Consider:

if isinstance(other, Distance):
    self.km += other.km
    return self
self.km += other
return self
