If there's going to be failure possible primality tests, there should also exist certain ones. No matter how slow it can be to do it.
Python if often a language for beginners. I think it'd be confusing to a lot of people that there's going to be tests that show "This one is probably prime", instead of sure tests. I'd call the functions is_prime() and is_likely_prime() (or is_likely_not_prime(), depending on where it fails), to make it really clear which you're picking and avoid confusion. 2018-07-13 10:21 GMT+02:00 Jeroen Demeyer <j.deme...@ugent.be>: > On 2018-07-13 04:02, Chris Angelico wrote: >> >> Haha.
