How Can I Remove Emojis from Strings in Python?

Removing Emojis from Strings in Python

The task of removing emojis from a string in Python can be achieved in several ways. One approach is to use the re.sub() function with an appropriate regular expression pattern. However, it's important to note that the given code may encounter issues when dealing with Unicode characters.

One possible solution involves using Python 2 and specifying the Unicode string literal using u''. Additionally, setting the re.UNICODE flag and converting the input data to Unicode ensures proper handling of Unicode characters. The following code demonstrates this approach:

<code class="python">#!/usr/bin/env python
import re

text = u'This dog \U0001f602'
print(text) # with emoji

emoji_pattern = re.compile("["
        u"\U0001F600-\U0001F64F"  # emoticons
        u"\U0001F300-\U0001F5FF"  # symbols & pictographs
        u"\U0001F680-\U0001F6FF"  # transport & map symbols
        u"\U0001F1E0-\U0001F1FF"  # flags (iOS)
                           "]+", flags=re.UNICODE)
print(emoji_pattern.sub(r'', text)) # no emoji</code>

Output:

This dog ?
This dog

Please note that the emoji_pattern matches only certain emoji and not all. For a more comprehensive list of supported characters, refer to "Which Characters are Emoji" documentation.
