如何打印数组中的回文和质数

def is_palindrome(num):
    # 判断是否为回文数
    str_num = str(num)
    reverse_str = str_num[::-1]
    return str_num == reverse_str

def is_prime(num):
    # 判断是否为质数
    if num <= 1:
        return False
    for i in range(2, int(num**0.5) + 1):
        if num % i == 0:
            return False
    return True

def print_palindrome_prime(arr):
    # 打印数组中的回文数和质数
    for num in arr:
        if is_palindrome(num) and is_prime(num):
            print(num)

# 示例数组
array = [12321, 12345, 131, 151, 22, 17, 23]
print_palindrome_prime(array)
