Euler项目，回文问题，未获得预期答案，python
a = []乙 = []for x in 范围(101, 999):for y 在范围内(101, 199):z = x * ya.附加(z)定义反向(n):n = str(n)如果 n == n[::-1]:n = int(n)b.附加(n)返回 bfor number in a:反向(数字)打印 max(b) 我的结果是 180181 但应该是 906609. 原来的问题是: “一个回文数的两种读法都是一样的.由两个 2 位数字的乘积构成的最大回文数是 9009 = 91 × 99. 找出由两个 3 位数字的乘积构成的最大回文数." 解决方案 我会保持简单: m = 0for x in 范围 (100, 999):for y in 范围(100, 999):z = x*yn = str(z)if n == n[::-1]:如果 m 打印(m)
