very bad kata

Main problem I do not see what falls this test. I see only problem, it do not show me 's', if i return 's' I so not see what my function do. I return 's' and return all 'false'. I do it. but for it need very much time. decition have ony one string, but you do not see it, if you do not know basic funtion for it

You've hadcoded the answer for several input values, but not all, read the error message:

expected undefined to equal false

Your code isn't failing the test of -0, it is failing another one, but as your code is wrong, it is not a kata issue. Make some code that works at least without hardcoding every test and only then open an issue if you're sure there is a problem with the tests.

Something is wrong with the basic tests (all randoms passed)

I printed all of the ones with a result of false, but as per the description they shouldn't be true? (Added an extra condition to make the -0 into true and still fails..)

"s2324" false
"3 4" false
"3-4" false
"3 4 " false
"-0" false

All tests pass, one fails. Shit! What do I do? I'm upset! Very upset!

Not a kata issue.

Your solution fails for s = " ".

fixed in latest fork after 6 years

Approved

python new test framework + snake_case + backward compatibility + updated random tests are required. updated in this fork

Printing the input: https://docs.codewars.com/training/troubleshooting#print-input

Sample tests are just that, a sample, it won't show all edge test cases.
