Can somebody help me with the random tests. What is the secret over there, they are definetely different...

Yeah, it should... But regardless all logic it returns false. Idk why, everything else seems works fine but this '1234' is fricking f up

Yeah, sure! I just googled some info bout typeof, therefore tried Number, but initially I had number. If you don't mind answering, do I really need to use try and catch or throw is okay in that case and the only mistake I made is the logical one?

Type 'Number' doesn't exist, only 'number' (not that it's the solution, but something you should know)

Sorry for that, I haven't seen your reply the moment I post the previous message. Thanks for telling me this!

Once again: USE A SPOILER WHEN YOU POST CODE.

I put the flag on for you twice.

I also gave you a link to format properly your code.

• If you don't understand something, it is not an issue (= a bug in the kata), ask a question;
• Please use a spoiler flag when you post code somewhere
• Use markdown tags to format your code or it's not usable. Refer to the documentation about this and more: https://docs.codewars.com/training/troubleshooting/#post-discourse

You don't need to try/except the error, just raise it.

You should use the raise keyword.

Print the input, see why your code fails that test.

hello, in prerequisites basic test i have a error "It should give an error for invalid input: True should equal False" but code is fine, all another tests passed. Work with Python, what do i do wrong?

Read the description again, 1 = 1

17935 # 1 + 7 = 3 + 5 // if the length is odd, you should ignore the middle number when adding the halves.
