simply because the sympy module is not available

from sympy import isprime as num
But Codewars doesn't accept import sympy as a valid solution :(

lol wow

Brilliant solution

That ELSE 'No' can't be a good practice

SQL code is not concrete poetry

Ah, angles are in Degrees

Can this kata even be solved?

here you are

oh, there's one last problem: call the user's function one time only per input => one time only at the beginning of the test function, then use the variable you stored to do the tests

switched it, thanks a lot

yeah, true, you can keep them (the assertion messages, I mean). But swith to assert_equals in any case. Currently, if the test fails, the user knows what you want, but not what he sents.

i think assertion message have to be anyway, because if i'm using type insted of isinstance default message will be <class '...'> should equal <class 'tuple'> for the first one and N should equal 2 for the second one, where N is the length of the output tuple. I think these messages are... not user friendly a bit, especially for the second one: user can't understand that N is the length of the output tuple

Pretty much yes. Just replace test.expect with test.assert_equals. This way you don't need the assertion message (use type instead of isinstance for the first one, so that you can ahve actual vs expected)
