Pairs of multiplied prime number--->N

[ibreeden]

4 by 8 dont return 10

You should test your program bit by bit. The first function should return a list of primes. Does it do so?

def prime_eratosthenes(lim):
    prime_list = []
    for i in range(2, lim + 1):
        if i not in prime_list:
            print(i)
            for j in range(i * i, lim + 1, i):
                prime_list.append(j)
                # print(j)
    return prime_list

lim = int(input("Generate prime numbers up to what number? : "))
print(prime_eratosthenes(lim))

Output:
Generate prime numbers up to what number? : 10
2
3
5
7
[4, 6, 8, 10, 9]

You can see the print() statement on line 5 does print the primes. But the returned list are not primes. Correct this first.
