使用Python过滤emoji表情符号的方法如下:
要过滤emoji表情符号,可以使用正则表达式来匹配和删除这些符号。以下是一个简单的Python代码片段,用于从字符串中移除emoji表情符号:
pythonimport re
def remove_emojis(text): emoji_pattern=re.compile([ u\U0001F600-\U0001F64F # emoticons u\U0001F300-\U0001F5FF # symbols & pictographs u\U0001F680-\U0001F6FF # transport & map symbols u\U0001F700-\U0001F77F # alchemical symbols u\U0001F780-\U0001F7FF # Geometric Shapes Extended u\U0001F800-\U0001F8FF # Supplemental Arrows-C u\U0001F900-\U0001F9FF # Supplemental Symbols and Pictographs u\U0001FA00-\U0001FA6F # Chess Symbols u\U0001FA70-\U0001FAFF # Symbols and Pictographs Extended-A u\U00002702-\U000027B0 # Dingbats ]+, flags=re.UNICODE) return emoji_pattern.sub(r'', text)
测试test_text=Hello 👋, this is a test 🚀 with some emojis 😊!filtered_text=remove_emojis(test_text)print(filtered_text)
这段代码定义了一个`remove_emojis`函数,它接受一个字符串`text`作为输入,并返回一个新字符串,其中不包含任何emoji表情符号。正则表达式`emoji_pattern`用于匹配所有emoji字符,然后使用`sub`方法将它们替换为空字符串,从而实现过滤。

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 redef 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 guyssoo ://gere comes one more video? Enjoy ♥️'
print('init:', text)
result = re_emojis(text)
print(result)init: Lamo see this edit guys?Hi guyssoo ://gere comes one more video? Enjoy ♥️
Lamo see this edit guys Hi guyssoo ://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
借用emoji过滤特殊表情
import emojiimport re
text = emoji.demojize('Lamo see this edit guys?Hi guyssoo ://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 guyssoo ://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。
