从 Python 中的字符串中删除表情符号 [英] removing emojis from a string in Python

问题描述

我在 Python 中找到了用于删除表情符号的代码，但它不起作用.你能帮忙处理其他代码或解决这个问题吗?

I found this code in Python for removing emojis but it is not working. Can you help with other codes or fix to this?

我观察到我所有的 emjois 都以 xf 开头，但是当我尝试搜索 str.startswith("xf") 时，我得到了无效字符错误.

I have observed all my emjois start with xf but when I try to search for str.startswith("xf") I get invalid character error.

emoji_pattern = r'/[x{1F601}-x{1F64F}]/u'
re.sub(emoji_pattern, '', word)

错误如下:

Traceback (most recent call last):
  File "test.py", line 52, in <module>
    re.sub(emoji_pattern,'',word)
  File "/usr/lib/python2.7/re.py", line 151, in sub
    return _compile(pattern, flags).sub(repl, string, count)
  File "/usr/lib/python2.7/re.py", line 244, in _compile
    raise error, v # invalid expression
sre_constants.error: bad character range

列表中的每一项都可以是一个词 ['This', 'dog', 'xf0x9fx98x82', 'https://t.co/5N86jYipOI']

Each of the items in a list can be a word ['This', 'dog', 'xf0x9fx98x82', 'https://t.co/5N86jYipOI']

更新:我使用了其他代码:

UPDATE: I used this other code:

emoji_pattern=re.compile(ur" " " [U0001F600-U0001F64F] # emoticons 
                                 |
                                 [U0001F300-U0001F5FF] # symbols & pictographs
                                 |
                                 [U0001F680-U0001F6FF] # transport & map symbols
                                 |
                                 [U0001F1E0-U0001F1FF] # flags (iOS)
                          " " ", re.VERBOSE)

emoji_pattern.sub('', word)

但这仍然不会删除表情符号并显示它们！任何线索为什么会这样?

But this still doesn't remove the emojis and shows them! Any clue why is that?

推荐答案

我正在更新 @jfs 对此的回答，因为我之前的回答未能说明其他 Unicode 标准，例如拉丁语、希腊语等.StackOverFlow 不允许我删除我以前的答案，因此我正在更新它以匹配问题的最可接受的答案.

I am updating my answer to this by @jfs because my previous answer failed to account for other Unicode standards such as Latin, Greek etc. StackOverFlow doesn't allow me to delete my previous answer hence I am updating it to match the most acceptable answer to the question.

#!/usr/bin/env python
import re

text = u'This is a smiley face U0001f602'
print(text) # with emoji

def deEmojify(text):
    regrex_pattern = re.compile(pattern = "["
        u"U0001F600-U0001F64F"  # emoticons
        u"U0001F300-U0001F5FF"  # symbols & pictographs
        u"U0001F680-U0001F6FF"  # transport & map symbols
        u"U0001F1E0-U0001F1FF"  # flags (iOS)
                           "]+", flags = re.UNICODE)
    return regrex_pattern.sub(r'',text)

print(deEmojify(text))

这是我之前的回答，不要用这个.

This was my previous answer, do not use this.

def deEmojify(inputString):
    return inputString.encode('ascii', 'ignore').decode('ascii')
