The same thing here !

I was confused with '?' after the type 'double' in the name of kata...

What aspect of this kata do you think they'd find confusing?

Please share some details what do you find ridicilous in the error checking.

Please also explain what is wrong - according to you - with the tags; the task in the kata is to write an encryption algorithm (=cryptography, ciphers)

Not kata-related.

me too! I am in the mainland china and i cannot view this picture.

description should be more clear now

rather about classes, I'd say... x) ;)

well, that's questionnable... The description isn't precise enough, imo. The original version is in JS where things are done differently. But one could considere that you're somehow failing this requirement instead:

You need to make a function that takes an object as an argument, and returns a very similar object but with a special property.

problem being: "similar to what point?"

answer: don't reinvent the wheel ;) (but that doesn't change the fact that the description might need a small update, at least about python)

you're actually not "failing the requirement", but you're failing the assertion because of the way it's done. Here it is:

test.assert_equals(your_object, original_dict)

gather your thoughts around this and try to think about what your implementation is missing.

The input and output of partial_keys should be equal.

The task was to reduce n to a single digit and check if that is very even or not. in that case 2+3+3 = 8, thus, very even

I grew up knowing about "hot toddy". basically heated whiskey, honey, and some herbs/spices. yeah, not for kids!
