while loop

[idddj]

So I was required to solve this question: Write a program to use a while loop to read the numbers from the user repeatedly until he/she inputs 0. Then report the sum of these numbers and the minimum value among them.

And my code for the sum part is like this:

sum1 = 0
n = int(input())
while n != 0:
    sum1 += n
print(sum1)

But when I run the code and input some integer, it does not show the sum although I have input a 0 lastly. Could someone tell me what the problem is in my code?
