过滤方法

Python怎么过滤 emoji表情符号呢？ 下面是剔除表情字符串的代码片段 python3.6下测试

import re
def re_emojis(text):
    emoji_pattern = re.compile("["
           u"\U0001F600-\U0001F64F"
           u"\U0001F300-\U0001F5FF"
           u"\U0001F680-\U0001F6FF"
           u"\U0001F1E0-\U0001F1FF"
           "]+", flags=re.UNICODE)
    return emoji_pattern.sub(r' ', text)
text = 'Lamo see this edit guys?Hi guyhttp://ssoo ://gere comes one more video? Enjoy ♥️'
print('init:', text)
result = re_emojis(text)
print(result)

init: Lamo see this edit guys?Hi guyhttp://ssoo ://gere comes one more video? Enjoy ♥️
Lamo see this edit guys Hi guyhttp://ssoo ://gere comes one more video? Enjoy ♥️

这里根据 unicode 范围来删除表情符号，通用的和IOS中的，不是很全，也没找到非常全的list。后面证实还是有写过滤不掉

使用emoji库过滤

终端安装emoji包

pip3 install  emoji

借用emoji过滤特殊表情

import emoji
import re
text = emoji.demojize('Lamo see this edit guys?Hi guyhttp://ssoo ://gere comes one more video? Enjoy the song Its just for fun guys dont take it far serious?Comment down your views and comment	? down for my next video♥️')
result = re.sub(':\S+?:', ' ', text)
print(result)

Lamo see this edit guys Hi guyhttp://ssoo ://gere comes one more video  Enjoy the song Its just for fun guys dont take it far serious Comment down your views and comment	  down for my next video ️

这样就过滤的超级干净了。
