Review Summary
I am requesting changes because there are still issues that conflict with the task requirements and checklist. The most important ones are: (1) in app/test_split_integer.py, the test that calls split_integer(0, 1) violates the requirement that the function takes two positive integers; this effectively tests behavior outside the specified input domain and may force extra validation that the task explicitly says is not needed. (2) In test_sum_of_the_parts_should_be_equal_to_value, you store the result in a parts variable and then assert on it; this is explicitly called out as a bad pattern in the checklist [CHECKLIST ITEM #1], and you can fix it by writing assert sum(split_integer(17, 4)) == 17 directly. These two items are both requirement-level issues, not just style preferences, so they need to be fixed before the solution is fully aligned with the task.
Critical issues to fix:
- Remove or rewrite the
split_integer(0, 1)test case so that all tests only use positivevalueandnumber_of_parts, consistent with the problem statement (e.g., focus instead on small but still positive values like1,2, etc.). - Inline the
split_integercall intest_sum_of_the_parts_should_be_equal_to_valueinstead of using an intermediatepartsvariable to comply with the checklist and keep the test as simple as possible.
Minor improvements (non-blocking but recommended):
- Add spaces after commas in function calls (e.g.,
split_integer(17, 4)instead ofsplit_integer(17,4)) and ensure each file ends with a newline so that flake8 passes cleanly. Overall, your tests are well-structured, usepytestcorrectly, and cover the key behaviors; fixing these points will bring them fully in line with the task and help you build even cleaner tests going forward.

This violates checklist item #1: "Don't create unnecessary variables for simple tests" — this test matches the Bad example pattern with parts = split_integer(...) followed by assert sum(parts) == 17. Consider calling split_integer directly in the assert.

The task specifies split_integer takes 2 positive integers, and "You don't need to validate arguments (they are always valid)". Using value=0 here contradicts that requirement and implicitly tests invalid input, which the function is not required to handle.

Review Summary
I am requesting changes because there is still a violation of a required checklist item in your tests, which makes this a blocking issue for this task. Specifically, in app/test_split_integer.py you have at least one assertion (the sum-of-parts test) that only checks the sum of the returned parts instead of asserting the full list returned by split_integer, which breaks [CHECKLIST ITEM #2]: the assert must directly compare the function result to the expected value. This can allow an incorrect distribution of parts to pass as long as the sum is right, so you should change that test to something like assert split_integer(value, parts) == [expected, list, here] for that input. Once that is fixed, your tests will be both functionally correct and checklist-compliant. As a minor (non-blocking) improvement, also address the flake8 style issues: add spaces after commas in app/test_split_integer.py and ensure both app/__init__.py and the test file end with a newline so the linter passes cleanly. Overall, your implementation and test coverage are solid; with these small but important adjustments you’ll fully meet the task requirements.

This assertion only checks the sum of the returned parts instead of comparing the function result with the expected list. This violates checklist item #2: "Make sure that you compare the result of function and expected result in assert statement." Consider asserting the exact list of parts you expect for this input.

Review Summary
Your solution is approved based on the current implementation and tests. The split_integer function correctly produces exactly number_of_parts integers, keeps the difference between max and min at most 1, and returns the parts in ascending order. Your tests in app/test_split_integer.py clearly describe the behavior being checked, directly compare split_integer(...) to explicit expected lists, and cover the key examples like 8,1, 6,2, 17,4, and 32,6, as well as a case where value < number_of_parts. This also aligns well with the checklist items about avoiding unnecessary variables and asserting the full function result against expected values.
I particularly like that the code is clean, free of extra prints or comments, and that you relied on simple integer division plus remainders to meet all constraints. Keep this level of clarity and directness in future exercises; it’s a solid pattern for both production and learning code.
