【中文标题】在推文中查找表情符号作为整个集群而不是单个字符【英文标题】：Find emojis in a tweet as whole clusters and not as individual chars 【发布时间】：2019-10-30 15:25:18 【问题描述】：

所以我在这里问过的第一个问题是关于表情符号的。对不起。

在Tweepy 和regex（也尝试过python-pcre）的帮助下，我正在用python 制作一个推特机器人，它将分析给定用户的推文，并记录单词或表情符号的次数被使用了。我可以很好地完成大部分工作。我的问题始于表情符号。

我的印象是，当使用 \X 时，（在 regex 和 python-pcre 中）会找到 eXtended 字形簇。不只是个别的。我在另一篇帖子What does the expression \X match when inside a RegEx? 中读到 \X 遵循一组准则来确定下一个字符是否应该被聚集，但总是至少返回 1。

我在这篇文章中尝试了第一个和第二个解决方案：How to extract all the emojis from text?。

第一个按预期运行。获取单个代码点并将它们添加到列表中。非常适合单个代码点表情符号，但我需要捕获具有多个代码点的表情符号和单个代码点表情符号。

第二种解决方案是我遇到问题的地方。根据帖子，此函数应以字符串、簇的形式打印表情符号，以空格分隔。

def split_count(self, text):
        emoji_list = []
        data = regex.findall(r'\X', text)
        for word in data:
            if any(char in emoji.UNICODE_EMOJI for char in word):
                emoji_list.append(word)
        return emoji_list

当这样调用时：

counter = self.split_count(tweet)
print(' '.join(emoji for emoji in counter))

应该导致：

???? ????‍????‍????‍????

但是当我运行它时，我得到：

???? ???? ???? ???? ????

100% 未聚集。

为什么会这样？这已经困扰了我几天了。

【问题讨论】：

奇怪的事实：当我将???? ????‍????‍????‍???? 粘贴到窗口中时，Windows 上的 Python 3.7 IDLE 崩溃。至于正则表达式，请注意\X 匹配单个代码点，但表情符号可能包含多个。您应该使用表情符号解析库。 【参考方案1】：

请注意，\X 匹配单个代码点，但表情符号可能包含多个，您自己在问题中提到它。

您应该使用已在使用的表情符号解析库从文本中提取表情符号。

使用re，不需要regex：

import re
from emoji import UNICODE_EMOJI

e_list = UNICODE_EMOJI.keys()
extract_emojis = re.compile("|".join(map(re.escape, sorted(e_list,key=len,reverse=True))))

#...

def split_count(self, text):
        return extract_emojis.findall(text)

请注意，使用此代码，针对包含来自Emoji List, v14.0 的所有独特表情符号的文件运行它，由于超时，我无法获得任何结果。

因此，要匹配那些最新的表情符号，您需要一个自定义正则表达式：
