def find_factors(num):
    factors = []
    for i in range(2, num+1):
        while num % i == 0:
            factors.append(i)
            num = num // i
    return factors

L = [2, 3, 7, 19, 23, 79, 83, 101, 193]
product = 1
for factor in L:
    product *= factor

print("乘积 =", product)

factors = find_factors(product)
print("乘积的所有因子（除1外）:", factors)

有大佬能解释一下这里的 for i in range(2, num+1) 吗？num变化了，可是i的范围为何没有变化？谢谢
