编写一个程序，查找离给定整数最近的回文数。定义函数find_closest_palindrome()，参数为num。在函数内部，返回最近的回文数。如果有两个回文数的绝对距离相同，返回较小的数。如果给定数字本身就是回文数，则返回该数字。示例输入 245 示例输出 242 解释:测试输入 245 的最近回文数是 242。2、代码实现：可编辑代码...
When the function reaches the end of iterable, minimum will hold the smallest value in the input data. Cool! You’ve coded a function that finds the smallest value in an iterable of numbers. Now revisit find_min() and think of how you’d code a function to find the largest value. ...
.from_bytes() Returns the integer represented by the given array of bytes .to_bytes() Returns an array of bytes representing an integer .is_integer() Returns TrueWhen you call the .as_integer_ratio() method on an integer value, you get the integer as the numerator and 1 as the denomin...
