Your ''.join() expression is filtering, removing anything non-ASCII; you could use a conditional expression instead: return ''.join([i if ord(i) < 128 else ' ' for i in text]) This handles characters one by one and would still use one space per chara
为什么要对字符串编码? 某些字符串中包含html标签,不编码,页面输出就乱了. PHP下怎么对字符串编码? htmlentities vs htmlspecialchars htmlentities 与htmlspecialchar 区别: htmlentities is identical to htmlspecialchars() in all ways, except with htmlentities(), all characters which have HTML character
在c++中检查字符串是否包含另一串字符串,这个本来是我做过的一个算法题,不过最近刚好有个需求让我想到了这个题,就在此记录一下! 使用std::string::findfunction string str ("There are two needles in this haystack."); string str2 ("needle"); if (str.find(str2) != string::npos) { //.. found. //如果不等,则说明找到一
移除重复字符很简单,这里是最笨,也是最简单的一种.问题关键是理解排序的意义: # coding=utf-8 #learning at jeapedu in 2013/10/26 #移除给定字符串中重复字符,参数s是字符串 def removeDuplicate(s): s = list(s) s.sort() #对给定字符串排序,不排序可能移除不完整 for i in s: while s.count(i) > 1: s.remove(i) s = "".join(s) #把列表
