my bad.
sorry.

very nice kata. learned something new.

Whats wrong with:

>>> wpp(4, 5, 4)
[(4, 0)]

??

Fails the test.

Description says: "the number of teams must be even"

EDIT:
If you understand the problem description, you should have a notion of what valid input is.
Please keep in mind this is not about formal specifications, but about having fun.

python, sorry.

In random tests length of ops must be one less than of string. However ops and string have the same length.

I think this kata can be insightful to people relatively new to OOP, and python in particular.

I noticed, when reviewing other solutions. ;)

Very concise solution. Impressed. Glad you liked it.

Thanks for your feedback!

Concerning the tests, you are absolutely right -- there should be more verbose messages. Explanation: I wrote them within the unittest framework, and rewriting them to fit the codewars framework was rather cumbersome. With an already working program at hand, I did not get a feel for the tests in the editor, anymore. However, the absolute number of tests is somewhat misleading, as assertions are reused e.g. when iterating through teams, and each assertion counts as a test.

However, I will add a subset of those tests to the test window. Thanks for pointing that out.

Concerning half-season vs. full-season, I am afraid I am missing your point. It certainly would not make sense to me if in a 'full-season' teams A and B would compete on days 1 and 2. On the other hand, when solving this kata, implementing full-season pairings becomes trivial.

Test failures do not include input strings. Therefore, there is some guesswork involved, but which made it more fun ;-)

As the cw currency is honor, I would suggest higher incentive. E.g., solving a kata while still in beta could return twice as much honor (or some other reasonable amount) than solving it after it has left beta.
