I have marked the kata as a puzzle.
This should now be resolved.
Marking as such.

If anyone feels like working with me on adding support for other languages, let me know!

I am trying to come up with ideas for python katas. Please can someone give me some ideas for them? Any help would be greatly appreciated!

The kata description says "Try using the Switch Statement".
I was initially confused with this because I am a python coder and python does not have a switch statement.
I think that adding a line saying "If your language supports it, try using the switch statement" or something similar would be more explanatory.

Due to the suggestion that this kata is not unique, I will be removing it entirely.

Thank you for your input @suic,
The function name has been changed.
The title of the kata has been changed to make it less obvious what conditional should be used.

Thank you for your input @zebulan,
Random string generation and testing is now added to the testing.
The test case error message has been fixed.
I will be posting more katas to do with more functions soon. (while, for etc.)

This has been successfully resolved.
Thank you for your input.
I have provied an example in the "Example Cases" area.
All of the tests are performed in the full test.

Apologies for the confusion.
I changed the actual test cases and not the example cases.
The issues should now be resolved.

Thank you for your input.
The test cases have now been fixed.

It says to work out the cost, excluding VAT. However, it does not tell you the rate of VAT that has been applied to the product in the first place.
