You really, really need to try harder.

I revoked your provoleges for creating new kata. You might get them back when you acknowledge the problems with your recently created content: unfinished descriptions, missing example tests, duplicates, etc. Your account might get suspended if you do not, and continue republishing unfinished kata.

Please stop authoring low quality katas and modify description from existing katas:

• This one is a dup of this which you've just solved not long ago

Also, your previous one is also a dup of this 8kyu and also this one of yours too

• Don't round float result, use test.approx_equals (https://docs.codewars.com/authoring/recipes/floating-point/)
• No sample tests (https://docs.codewars.com/authoring/guidelines/sample-tests/)
• No it blocks (https://docs.codewars.com/languages/python/codewars-test)

You'll need more than one fixed test in your submission tests.

Missing example tests

Random tests are broken as reference solution incorrectly handles uppercase letters.

Bad random tests. They never expect None.

No fixed tests.

actual and expected are switched in their definitions, but not in assert_equals, so failure messages are the wrong way 'round.

Looks like a duplicate of https://www.codewars.com/kata/513e08acc600c94f01000001

• Missing Example Tests
• No fixed tests
• Submission Tests not properly implemented

Please read the docs on authoring kata: https://docs.codewars.com/authoring/tutorials/create-first-kata

The random tests capture the same mutable variable by reference.
