The Kata is compatible with Python 3.6.0 as of 28/01/2020.

Thanks @gayanw!

That test [[True]] is still there. It should be removed, or accepted as valid. In the end it is still [[1]]

No issue now.

It is still there. Just search by his name. BTW he linked to this: http://blog.ostermiller.org/find-loop-singly-linked-list

Seems not applicable anymore

Yes, it should.

It's been a year.

If the issue was not resolved, please reraise it.

Closing.

The matrices involved in the kata are all integers so clearly the determinant is also a integer, you shouldn't return a float at all.

So... round? ;-)

Same. Solved in C#.
Don't think it can be language since we can see eachother's comments.

You probably figured this out by now, but python3 doesn't have xrange. use range instead.

You need to think about rounding in this kata.

Thanks for the feedback. I added a note in the description to indicate that for 0x0 grids, an empty path list is expected.
