index(str, beg=0, end=len(string)) 跟find()方法一样,只不过如果str不在字符串中会报一个异常。 str.isalnum() 如果字符串str至少有一个字符并且所有字符都是字母或数字则返 回 True,否则返回 False str.isalpha() 如果字符串str至少有一个字符并且所有字符都是字母或中文字则返回 True, 否则返回 False...
Given a string S, find the longest palindromic substring in S. You may assume that the maximum length of S is 1000, and there exists one unique longest palindromic substring. ===Comments by Dabay=== 从最长的字符串开始判断,直到长度为2。但是这样的算法会超时Time Limit Exceeded。
