Interesting to decode and to figure out.

Finally, a good excuse to play with the walrus operator!

The kata has only Python, but yes, claiming there is an impossible test with no other information isn't right.

I would fix this test case if you told what is the test case you found impossible. Or at least in what language.

One test case I found looks impossible.
There is no way for it to be made using the encoding function! I don't understand how people completed this kata.

no, you are thinking about encryption, not encoding.

not sure whether this is intended or not, but doesn't displaying the encoding function make this a simple hash map kata and not really a decoding one?

.

Could you explain why you authored an exactly same kata having the exactly same issues a second time instead of fixing the original one?

No describe/it blocks in sample tests

Thanks for a link, gonna fix that in my free time. It is my first kata and i was sure that i will make mistakes

Thanks, gonna correct that in my free time.

In description: exmaple should be example.

• No describe/it blocks
• No fixed tests
• Encoding function should be nested in test function (not in preloaded)
