WebSo to find out if a given number is prime or not, we just have to keep dividing it by integers and see if any of them evenly divide the number with 0 remainder. The math.sqrt () function will return a float value of the square root of the number it is passed. The square root of a number can be multiplied by itself to get the number. Webdef primes (n): primes = [2] attempt = 3 while len (primes) < n: if all (attempt % prime != 0 for prime in primes): primes.append (attempt) attempt += 2 return primes [-1] Note, you also forgot to increment attempt when a prime was found.
