OP solved it, closing

Hi. There must be a problem with your code ; tests expect False in this case, I've just run my solution and it works fine, this kata has been completed more than a 10000 times... You can post your code with a spoiler flag to get further help.

[1, 3, 2, 5, 7, 9, 4, 6, 8]
[4, 9, 8, 2, 6, 1, 3, 7, 5]
[7, 5, 6, 3, 8, 4, 2, 1, 9]
[6, 4, 3, 1, 5, 8, 7, 9, 2]
[5, 2, 1, 7, 9, 3, 8, 4, 6]
[9, 8, 7, 4, 2, 6, 5, 3, 1]

True should equal False

Columns 8 and 9 have duplicate values (3 and 5 respectively). When I run in Virtual Studio (Python version 3.9) I get False. When run in codewars it comes back as True. The data set I've attached above is directly above the error "True should equal False. Is anyone able to assit? Kata attempted in Python. Thanks

Hi. Please say the language you're using when you ask something related to you code. If Python you can print the arguments to the screen with print.

is there a way to view "Basic Test" input? receving the following output: "Passed: 57 Failed: 1 Exit Code: 1"
