k=2;
sum=0
print('The list of the prime numbers are as follows:')
# This loop runs from k to n
while k<=n:
# Call is_prime() method,
# to check whether k is a prime or not
sum=sum+is_prime(k)
k=k+1
print('Sum of the prime numbers:',sum)
# is_prime() Method
def is_prime(k):
prime=0
i=1
# Check k is a prime or not
while i<=int(k):
# Find the factors of k
if (k % i) == 0:
prime=prime+1
i=i+1
# If k as two factors
if(prime==2):
print(k)
return k;
# If k as more than two factors
else:
return 0;
# Call the main() method
