41. Code project in Data Science

Question

My code pass tests 1,2, 4 and 5 but it does not pass test 3. Input for tests from 3 to 5 are hidden. Any ideas?

Answer 1

See the syntax correctly

Answer 2

'if none of the data points were assigned to the given centroid, return None'
So I returned new array or "None" but test 3 is still wrong
