Hey, It's my initial value is wrong, my solution was passed,thank you so much, have a good day!

Thanks,I go to try it!

Initial value of scores is wrong.
Test your function with "ba aaa" and see what it returns.
Don't use max as a var name, it has a special meaning in Python.

Although my comment above focuses on the negative, personally, I think that this is a good kata because it gives a real-world situation for doing the dot product. There are many ways to do a dot product, so it gives us practice thinking about it.

As it is, some people are challenged not by the underlying problem itself, but by the description of the problem. I like that example, @Chrono79, and think that it could strengthen the description.

Alternately, you could just write it out in words.

Each race has a certain worth when battling against others.

That should cover the common error, but if a test was added in the sample tests it would be fine by me. Or adding this example to the description:

     Good                                       Evil

 0 0 0 0 0 1                   /            0 0 0 1 1 1 0
    Wizard                     /       Goblin + Uruk Hai + Troll
      10                       /         2    +  3       +   5
      10                       /               10                           

10 = 10 therefore it is a draw

Maybe it's just "Evil", not bad!

a bad kata!!!
