It only fails because they used division ('/') instead of floor division ('//') the one you need is explained in the instructions. The failures occur because it is expecting a result rounded down to the nearest whole number and is instead giving a decimal answer in certain tests.

It is a good example of how lambda expressions can be used though. This solution enlarged my perspective.

short code != fast code, Just a half-ass attempt on code golfing 😜

this is O(n²)

How?

Yes, the check on this line will pass. But column and segment checks will fail. Because the only way to get 45 from different numbers from 1 to 9 is 1+2+3+4+5+6+7+8+9.
Look at my solution. It works. Everytime

1+1+1+5+5+5+9+9+9=45

However, this is not a valid row/column.

1+2+3+4+5+6+7+8+9=45

You should have checked to see if the sum of the list is 45. You don't have to keep checking the list of numbers from 1 to 9
