It is worth noting that using re.match instead of re.search provides, essentially, an implicit ^ to the regex argument. So, it could be left out in this instance.
Please, do use the spoiler flag when you post comment (even here: comments about solutions are visible in the dashboard by anyone) with indications about the solution. I did flag your message.
Right... Good call. In that case, the sales table should have a default for the department id field set to 0, and then the unknown row would have an ID of 0
It probably means that your solution doesn't work with integer string values as described in the problem description. Your solution returns [1.0, 2.0, 3.0] for parameter array ["1", "2", "3"] whereas it should return [1, 2, 3]. The test set seems to be a bit lacking as they are not testing this case.
just try it and you'll realize that will awefully fail the performance tests.

I went through all my previous comments and marked them as spoiler as needed.
Thanks for letting me know. I assumed everything in the solutions section was hidden from anyone who hadn't completed the kata.

Because id cannot be null in table departments (cause PK), then no values will be provided for result.
If the db is built properly, the departments table would have a null row that would have the name "Unknown"
And what happens if the department_id field of the sales table is null your solution falls.
eval() is now disabled
