Review Summary
Good work on the overall structure and implementation of the Person class. The use of list comprehension is also well done.
However, this requires a change due to a critical functional issue. The Person.people class attribute is never cleared between calls to create_person_list. This causes data from previous calls to persist, leading to incorrect outputs if the function is run more than once. To fix this, you should clear the Person.people dictionary at the beginning of the function.
Additionally, while not a blocker, the code for linking spouses could be simplified by using dict.get() to fetch the person object, which is the recommended approach. [CHECKLIST ITEM #4]

The Person.people dictionary is a class attribute and is never cleared. If this function is called multiple times, it will accumulate Person instances from all previous calls, leading to incorrect results. Consider clearing this dictionary at the beginning of the function to ensure it works correctly for multiple independent calls.

This violates checklist item #4: 'When accessing values in a dictionary, it is better to use the dict.get() method instead of explicitly checking for the presence of a key.' You can simplify this logic by using Person.people.get(wife_name) and then checking if the result is not None before assigning it.

This violates checklist item #4: 'When accessing values in a dictionary, it is better to use the dict.get() method instead of explicitly checking for the presence of a key.' Similar to the wife attribute, you can simplify this by using Person.people.get(husband_name) to retrieve the husband instance.

Review Summary
Great job fixing the critical bug from the last review by clearing the Person.people dictionary! The code is now functionally correct. However, one change is needed to fully align with the project's guidelines. The spouse-linking logic currently uses an in check on Person.people before accessing the value, which violates a checklist item [CHECKLIST ITEM #4]. You can simplify this by using Person.people.get(spouse_name) to retrieve the spouse's instance and check if the result is None in a single step. Please apply this pattern to finalize your solution.

This violates checklist item #4, which recommends using dict.get() instead of checking for key presence with in. You can simplify this by attempting to .get() the wife's instance from Person.people directly using wife_name as the key, and then checking if the result is not None. This same pattern should be applied to the husband-linking logic below.

Review Summary
Excellent work! I am approving your solution as it's now perfect. You've successfully addressed the feedback from the previous review by using dict.get() for spouse linking, which aligns perfectly with the project's guidelines [CHECKLIST ITEM #4]. The code is now clean, efficient, and fully compliant with all requirements. Great job finishing this up!
