That's just a long variant of is_probable_prime()
That's besides the point. I agree that probable primes are good enough, just don't call them "prime".
Should we call sort then probable_sort, since the non-zero probability exists of it going wrong due to a stray cosmic ray? It's pointless to worry about failure modes which are order of magnitudes unlikelier than hardware failure. Stephan Op vr 13 jul. 2018 14:45 schreef Jeroen Demeyer <J.Demeyer@ugent.be>:

And in the interests of full disclosure, we should call Python a probable language, running on a probable computer. -- Probable Greg
I think the extra 9 characters of "_probable" are worth the extra accuracy. Dont teach people to lie in their function names. It's a bad example. and if you really want to lie, just from imath import is_probably_prime as is_prime 2018-07-13 14:44 GMT+02:00 Jeroen Demeyer <J.Demeyer@ugent.be>:
