Prime factorization - list

Question

I am trying to implement a function primeFac() that takes as input a positive integer n and returns a list containing all the numbers in the prime

Answer 1

prime factors of a number:

def primefactors(x):
    factorlist=[]
    loop=2
    while loop<=x:
        if x%loop==0:
            x//=loop
            factorlist.append(loop)
        else:
            loop+=1
    return factorlist

x = int(input())
alist=primefactors(x)
print(alist)

You'll get the list. If you want to get the pairs of prime factors of a number try this: http://pythonplanet.blogspot.in/2015/09/list-of-all-unique-pairs-of-prime.html
