Question:
The sum of the primes below 10 is 2 + 3 + 5 + 7 = 17.
Find the sum of all the primes below two million.
Code:
import math def IsPrime(n): if n==1: return False else: i = 2 while n%i!=0 and i<=math.sqrt(n): i += 1 if i<=math.sqrt(n): return False else: return True print(sum([i for i in range(2,2000000) if IsPrime(i)]))
