所谓回文数 Palindrome Number,即从左边开始读或从右边开始读,两者结果一致。判断的目标数字为整数,包括负数。 比如12321,123321,或者 3,都是回文数。 -12321不是回文数;-1也不是回文数。 解法1. 简单解法:将整数转换为字符串 转换之后,Python有转换的 reverse 函数,将字符串进行反转:str[::-1]。

Program for Palindrome number in Python A palindrome number is a number or a string that when reversed, remains unaltered. num = int(input("Enter a number")) temp = num rvrs = 0 while(num>0): dig = num%10 rvrs = rvrs*10+dig num = num//10 if(temp == rev): print("The numb...
) else: print("The string is not a palindrome.") Run Code Output The string is a palindrome. Note: To test the program, change the value of my_str in the program. In this program, we have taken a string stored in my_str. Using the method casefold() we make it suitable for ...
