• Function name should be in camel_case
• You need to add random tests
• New python test framework should be used, and solution should be imported explicitly
• Your kata lacks novelty

Have you read the documentation about creating kata?

nice kata!

Edit: if i were to reverse the input, its obvious ill get a different string as the output but of same length. i think the description should be changed to, so that output depends on the order too.

Random tests:

'scnrlvusuyngiautwthmkwdzlmkprubgqjamcxngcuwluaejiprv' should equal 'dehiobmntrnunstsutidsahjivtpoxwdlsnrbmresbnlsrgzqber'

It has the same length.

• No sample tests

• No random tests

• Don't put a print statement in assertions (no point of doing that) !

Maybe you can read this & this for better authoring in future which is just in the left sidebar, ^_^
