The tests are alright, and Python 3 is available now.

!

Reminder: Python 2 will be retired in 2 months, see: https://pythonclock.org/
So it is completely reasonable to not only open for but switch all katas to Python 3.

I think what you see is "honors". Honors give you ranks and privileges. See:
https://github.com/Codewars/codewars.com/wiki/Honor-&-Ranks
https://github.com/Codewars/codewars.com/wiki/Privileges

Badges are already earned when you get enough honors. They are shown in the "Profile badges" section accessible by pushing the "View Profile Badges" button in your profile page.

There're no such test cases in JS. You must be mutating the input.

Good point! I've added negative tests throughout. Thanks for the help.

@Todosio I've raised an issue for that on codewars site please take a look https://github.com/Codewars/codewars-runner-cli/issues/667

no valid for mysql 5.7 only postgres.

1. Reference to an older instance should be returned.
2. Yes, creating an instance, whether you save it in a variable/lookup table or not, counts towards the number of created instances.

Please check again

Sorry, it seems that I have forgotten. Nobody said something before you:-( Fixed, thanks.

None of the two mentioned is an issue, and I'm rather getting tired of ppl who don't know that they are wrong and instead blame the world. So I'm gonna explain this (and hope you actually get it) :

• The error won't accour, what you are seeing is simply CW putting \ before string (like it should) the real test is :
  • b <- 0 ? "sometjing" + "someibt" : "sa"

As you can see, your BS is nothing but dumbness on your end (how'd you hit 4Kyu and still be unable to read CW console ? )

• I put this in 2 calculators the answer I get is : 0.00908480467 which is perfectly what it is. there is no rounding error and can't possibly be a rounding error (we are not doing a math problem here), there is no different style being tried.

I strongly suggest that you rethink what you are doing and don't open bogus issues. Thank you. rest assured my tests are fine and perfectly thorough.

Also down-voting comments is no fun but you are more than welcome to down-vote them if it helps you feel better. All my comments can be found in my profile, feel free to downvote any and all :)

Let me know if you still are having any issues.

A detailed explanation of how the first problem is solved (to assure I don't have to tell you again) :

STEP 1 : 
solving the side before the (/). i.e : (1+2*(9-8)/1-5+8)

=> 1 + 2 * 1/18 + 4
= 1 + 2/18 + 4
= 1 + 1/9 + 4
= 10/9 + 4
= 46/9
= 5.111111...

Solving the side after (/) i.e : 21 * 9/3 * 9 - 1 * 4.4)

=> 21 * 3 * 9 - 4.4
= 567 - 4.4
= 562.6

5.11/ 562.6
= 0.009084804677

hence proved. have a good day

First, added floor in order to remove possibility of error

second the expected answer is given, your code is unable to achieve result

(also you shouldn't have had problem with first as well)

anyway resolved
