Python:如何将约数分类为复合和质数？

def is_prime(num):
    if num < 2:
        return False
    for i in range(2, int(num**0.5) + 1):
        if num % i == 0:
            return False
    return True

def classify_divisors(n):
    prime_divisors = []
    composite_divisors = []
    for i in range(1, n + 1):
        if n % i == 0:
            if is_prime(i):
                prime_divisors.append(i)
            else:
                composite_divisors.append(i)
    return prime_divisors, composite_divisors

# 示例使用
number = 30
prime_divs, comp_divs = classify_divisors(number)
print(f"质数约数: {prime_divs}")
print(f"复合数约数: {comp_divs}")
