Why this is not duplicate? Other than in the linked kata you've invalid operations and float division.

This lacks all originality and novelty.

Please unpublish this kata.

Please use new python test framework.

there are many such kata that have the same logic, that of a "singlton positive" (one result only gets a different outcome):

... and these were found without trying that hard, there are bound to be many other duplicate scenarios.

This kata is too easy and there a lot of katas that look very similar and the estimated rank is 7kyu but it's basic stuff, change it to 8 kyu

Here is a kata that is similar

no random tests

• No explanation what each function should do
• New test framework should be used
• No tests for the helloworld function
• No random tests
• A bugfixing kata where rewriting the code from scratch is easier than fixing anything is a poor kata
