For the archives, that code is:
num = 13195
#num = 600851475143L
prime_numbers = [2]
prime_factors = []
for i in range (2,num):
for j in prime_numbers:
if i % j == 0:
break
else:
prime_numbers.append(i)
print 'The Prime Numbers are : ', prime_numbers
for items in prime_numbers:
if num % items == 0:
prime_factors.append(items)
print 'The prime factors are : ' , prime_factors
In the future, please avoid the unnecessary indirection of pastebins
when your code is relatively short. Including the code directly in
your post is also likely to increase the response rate you get.
Cheers,
Chris
