关于#for#的问题，如何解决？

Question

for i in range(100,1000):
if str(i)[0]==str(i)[2]
and (int(i[0]+i[1])+i[2])%10==0:
print(i)

#我想取出100-1000中所有回文数并且这三个数加起来还要是10的倍数，但是给我报错TypeError: 'int' object is not subscriptable，请大佬解释一下~

Answer 1

i还是整数好吧，又不是字符串，怎么根据下标取值？

for i in range(100, 1000):
    a = str(i)[0]
    b = str(i)[1]
    c = str(i)[2]
    if a == c and (int(a) + int(b) + int(c)) % 10 == 0:
        print(i)
