Answer 1

data = list(range(1, n + 1))

def Prime(n): 
    for i,v in enumerate(range(2, n // 2 + 1)):
        for j in data[i+2:]:
            if j % v== 0 :
                data[j-1] = 0
    return list(filter(lambda x: x != 0, data))

print(data[::2], data[::2][::-1])
print(data[1::2], data[1::2][::-1])
print(Prime(n)[1:], Prime(n)[1:][::-1])
