编写首先添加输入值的python程序，然后检查新值是否为素数

Question

我正在尝试用Python编写一个程序：

1. 添加输入。假设输入为123，它将添加它并给出输出（1 + 2 + 3）6
2. 检查输出（6）是否为素数

这就是我一直在做的事情，但它似乎不适用于需要首先执行添加的10以上的数字。

def prime_digit_sum(number):
    n = (number)
    temp = n = int(n) 
    remainder = sum = 0 
    while (  temp > 0) :
            remainder = temp % 10
            temp = temp/10
            sum= sum +remainder

    if number == 2:
        return 1
    elif number == 3:
        return 1
    if number <= 1 or number%2==0:  
        return 0  
    check=3  
    maxneeded=number  
    while check<maxneeded+1:  
        maxneeded=number/check  
        if number%check==0:  
            return 0  
        check+=2  
    return 1  

while(True):
    text = input("please enter an integer: ")
    if (text == 'q'):
        break
    number = int(text)

    result = prime_digit_sum(number)
    if (result == None):
        continue
    if result:
        print("the sum of digits of", number, "is a prime number")
    else:
        print("the sum of digits of", number, "is not a prime number")

    print()

print("exiting")
