Duplicate Kata
Thank you , I've been able to change the code. @chrono79
I need help, my code does exactly what it's supposed to . But its not passing me I don't understand
A problem with your code is not a kata issue, please read this: https://docs.codewars.com/training/troubleshooting
Your code is wrong btw.
python fork with new test framework
Approved
This one a bit tricky.

Your code is wrong, 8177 is not a prime number. It's divisible by 13. Not a kata issue. Read this please: https://docs.codewars.com/training/troubleshooting/
Thanks for your explanation
Java Translation kumited :) Please check and approve ~~
Python reference solution is flawed; even numbers are not prime.
fixed :) and i PM u asking about something, do go and check
ruby translation kumited :) Please check and approve ~~
Please see issue above for Python. (the translation can't be approved yet)
no random tests in python
added
javascript translation Kumited! Please Accept :D
Approved fork

Please add a power of two to the test cases. That would invalidate incorrect solutions like this, which don't check for divisibility by two.
For n = 12, my solution fails and I get this
Expected: true, instead got: false Isn't this wrong ? Similar is the case with n = 25
Another bugged test case: None should equal False
If '0' or 'None' is passed the function returns False. However, it errors out on submit.
Don't see what's the problem.
Maybe put a really large prime in there so doing an odd range of 3 to n would be extremely slow.
To make this kata more difficult, you could put a computational time limit on it and test some very large primes. This would make testing n / every odd number from 3 -> sqrt(n) infeasable.

Thanks, I just added it.
What about input restrictions? Solutions for small integers would be completely different from big ones.
The description should include that only non-negative values are tested. I'd add tags 'Numbers' and 'Mathematics'.
Thanks, updated.
