为什么不试试神奇列表呢？

lst1 = list(map(int, input().split( )))
lst2 = ['one','two','three','four','five','six','seven','eight','nine']
if 1 <= lst1[0] + lst1[1] <= 9:
    print(lst2[lst1[0] + lst1[1] - 1])
else:
    print('None')

空间换时间

#include<stdio.h>
char arr[10][10]={"None","one","two","three","four","five","six","seven","eight","nine"};
int main(){
	int a,b;
	scanf("%d %d",&a,&b);
	a+b>=1&&a+b<=9 ? printf("%s",arr[a+b]) :printf("%s",arr[0]);
	return 0;
}

用switch做就可以了
