Reraised as issue with more detail

Fixed by last python update.

finally approved :)

First line run, minimum of arr is 1, arr.index() returns the first index (searching from the left) of an occurrence of 1, which happens to be 0. m gets 0.

Next, sorted() is called on arr and returns a new sorted array, [1,1,2,3,4]. On the other side, arr[m:] with m=0 becomes arr[0:] gives [1,2,3,4,1]. arr[:m] with m=0 becomes arr[:0] gives []. [1,2,3,4,1]+[] gives [1,2,3,4,1]. [1,1,2,3,4] == [1,2,3,4,1] evaluates to False.

A bit late but i have now approved it!

oh hell yeah, I'll join it, that sounds like a much better workflow

Also, I forgot to add: there is a #help-author channel on the Codewars Discord when you can ask for help/advice, or get people to review your draft katas before publishing them; this can help you iron-out any early problems (and also determine if your idea is judged "interesting" enough before you spend hours working on it).

You're welcome, glad it was useful;

Note also that you can read the Test Cases of any kata you have solved - recently approved katas, or ones with high approval ratings can be a good source of inspiration if you want to get a feel for the Codewars test suite, and good practices (it's how I figured this stuff out myself).

Best wishes for your kata authoring in future, I hope you stick with it!

this is a HUGE help, obviously for this Kata but also to understand for future Katas. If I can get this process down I think I'll really enjoy writing them :)

hello sir-- I wrote random tests but not sure about the syntax to execute-- would you help me please? It's my first Kata and I can't find the syntax in docs/Google...

Many thanks in advance!

The python code works fine, but the test execution syntax is throwing an error:

File "/workspace/default/tests.py", line 45
    test.assert_equals(matt(test_list[0]), solution(test_list[0])
                                           ^^^^^^^^^^^^^^^^^^^^^^

        # our new string

        # picks random characters according to the length of the string
        for i in range(0, length_of_string):

    test.assert_equals(matt(test_list[8]), solution(test_list[8])
    test.assert_equals(matt(test_list[9]), solution(test_list[9])

thank you! I'll fix it up :)
