А что за это будет?

 

1-ое, но нашел в инете, проверь сам

def prnum(n) :
prime = [True] * (n+1)
prime[0] = prime[1] = False
prime[2] = True
for j in range(4, n+1, 2):
prime[j] = False
for i in range(3, n + 1, 2) :
if not prime[i]:
continue
for j in range(i * i, n+1, i):
prime[j] = False
i += 2
return prime
n = int(input())
pr = prnum(n)
res = 1
for i in range(1, n+1) :
if not pr[i] :
res *= i
print(res)

Код

def prnum(n) :

    prime = [True] * (n+1)

    prime[0] = prime[1] = False

    prime[2] = True

    for j in range(4, n+1, 2):

        prime[j] = False

    for i in range(3, n + 1, 2) :

        if not prime[i]:

            continue

        for j in range(i * i, n+1, i):

            prime[j] = False

        i += 2

    return prime

n = int(input())

pr = prnum(n)

res = 1

for i in range(1, n+1) :

    if not pr[i] :

        res *= i

print(res)

2-ое я так и не пойму: двумерный или одномерный, как скажешь, помогу или найду

 

2:

def multiplicity(n: int) -> int:
a = 0

for num in range(1, n+1):

if num % 3 == 0 or num % 5 == 0:
a += 1

return a

Python

def multiplicity(n: int) -> int:

    a = 0

    

    for num in range(1, n+1):



        if num % 3 == 0 or num % 5 == 0:

            a += 1

            

    return a
