Hi, I made a Python translation for this kata. Please approve it.

There are solutions, like this one which should not pass as the upper bound of the length of a and b is not specified and potentially infinite.

My suggestion is to test bigger arrays of random size in the random tests.

Edit: Kata specifications say "The lengths of the first two arrays will be equal, and the integers will always be positive", but the last fixed test uses [0, 0] as an array.
