• Imports for solution and codewars_test are missing.

• Tests should use python test framework: https://docs.codewars.com/languages/python/codewars-test

• missing import, missing test.it blocks

• Lack of novelty

Neat kata! I rarely explore unusual use cases for decorators, so I'm always happy to see something new.

It's start:stop:step
Here it means start at the 2nd element (index 1 in base 0) then take every other element (step of 2).

stop is empty so default is until the end of the string.

could you please explain the slicing method st[1::2] ?
Thanks

Just select Python 3.8 at the top page.

Am unable to run tests. Even after resetting, I get this error:

Traceback (most recent call last):
  File "main.py", line 1, in <module>
    from solution import *
  File "/home/codewarrior/solution.py", line 1, in <module>
    from setup import *
  File "/home/codewarrior/setup.py", line 2, in <module>
    import codewars_test as test
ModuleNotFoundError: No module named 'codewars_test'

Yeah, to be clear I did submit a proper solution before this one (just realized whilst I can still see it I'm sure if others can?)

As ideally invalid solutions would be caught by tests (but that is hard to do) I find it an interesting challenge to try and sidestep them once I've completed the challenge properly.

"you are not allowed to use the lru_cache decorator from the functools module for this task."

Working on this Kata makes decorators more accessible.

Very recommended.

Great kata! Now I have much better understanding of decorators :)

really nice kata. helps a lot if you want to see if you understand decorators in python.

that's what i like about codewars. it has some exercises that could be useful in a real application and not just acedemic purpose.

I think the description should be clearer, I'm not sure if I enter n and use the first function, whether the first n numbers should be returned, or all but the last items with value of n should be returned.

Apparently, you should reload this kata, so there isn't so much information - I've changed it.
