What a boring algorithm bad work

well, you solved this without regex, which is already impressive.

Specs of the python tests are slightly different from the original language: the random tests generate words without any vowel.

All languages should be aligned:

• either this should be added to the fixed tests and random tests in all language
• or python random tests should not generate such a kind of input

Approved.

It's all fun and games until you see this kind of authentication system in production.

I think this kata should be retired since what it "teaches" can result in massive security nightmares.

1. the provided solution is invalid, since the description specifies that hex is 3 or 6 hexadecimal characters (no leading #)

2. this also has the same problem as your JS fork: you don't randomize the generated test cases, so one can easily see the pattern (that is, 50 true + 50 false) and just hardcode it

1. uses Codewars's deprecated test framework instead of Mocha/Chai
2. since you don't randomize the generated test cases, this solution passes:

const cases = [
  ...[...Array(6)].fill(true),
  ...[...Array(5)].fill(false),
  ...[...Array(50)].fill(true),
  ...[...Array(50)].fill(false),
];

function isHex(str) {
	return cases.shift();
};

You're right.
I just didn't know that float(...) ignores surrounding whitespaces.
There is always something new to learn😀
