How to extract all the emojis from text?

Answer #1:

You can use the emoji library. You can check if a single codepoint is an emoji codepoint by checking if it is contained in emoji.UNICODE_EMOJI.

import emoji

def extract_emojis(s):
  return ''.join(c for c in s if c in emoji.UNICODE_EMOJI)

Answer #2:

I think it’s important to point out that the previous answers won’t work with emojis like ??????? , because it consists of 4 emojis, and using ... in emoji.UNICODE_EMOJI will return 4 different emojis. Same for emojis with skin color like ??.

My solution includes the emoji and regex modules. The regex module supports recognizing grapheme clusters (sequences of Unicode codepoints rendered as a single character), so we can count emojis like ???????

import emoji
import regex

def split_count(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

Testing (with more emojis with skin color):

line = ["? ? me así, se ? ds ??? hello ???? emoji hello ??????? how are ? you today????"]

counter = split_count(line[0])
print(' '.join(emoji for emoji in counter))

output:

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

Edit:

If you want to include flags, like ?? the Unicode range would be from ? to ?, so add:

flags = regex.findall(u'[U0001F1E6-U0001F1FF]', text) 

to the function above, and return emoji_list + flags.

See this post for more information about the flags.

Answer #3:

If you don’t want to use an external library, as a pythonic way you can simply use regular expressions and re.findall() with a proper regex to find the emojies:

In [74]: import re
In [75]: re.findall(r'[^ws,]', a_list[0])
Out[75]: ['?', '?', '?', '?', '?', '?']

The regular expression r'[^ws,]' is a negated character class that matches any character that is not a word character, whitespace or comma.

As I mentioned in comment, a text is generally contain word characters and punctuation which will be easily dealt with by this approach, for other cases you can just add them to the character class manually. Note that since you can specify a range of characters in character class you can even make it shorter and more flexible.

Another solution is instead of a negated character class that excludes the non-emoji characters use a character class that accepts emojies ([] without ^). Since there are a lot of emojis with different unicode values, you just need to add the ranges to the character class. If you want to match more emojies here is a good reference contain all the standard emojies with the respective range for different emojies http://apps.timwhitlock.info/emoji/tables/unicode:

Answer #4:

The top rated answer does not always work. For example flag emojis will not be found. Consider the string:

s = u'Hello U0001f1f7U0001f1fa hello'

What would work better is

import emoji
emojis_list = map(lambda x: ''.join(x.split()), emoji.UNICODE_EMOJI.keys())
r = re.compile('|'.join(re.escape(p) for p in emojis_list))
print(' '.join(r.findall(s)))

Answer #5:

Another way to do it using emoji is to use emoji.demojize and convert them into text representations of emojis.

Ex: ? will be converted to :grinning_face: etc..

Then find all :.*: patterns, and use emoji.emojize on those.

# -*- coding: utf-8 -*-
import emoji
import re

text = """
Of course, too many emoji characters 
? like ?, #@^!*&#@^# ? helps ? people read ?aa?aaa?a #douchebag
"""

text = emoji.demojize(text)
text = re.findall(r'(:[^:]*:)', text)
list_emoji = [emoji.emojize(x) for x in text]
print(list_emoji)

This might be a redundant way but it’s an example of how emoji.emojize and emoji.demojize can be used.

Answer #6:

The solution to get exactly what tumbleweed ask, is a mix between the top rated answer and user594836’s answer. This is the code that works for me in Python 3.6.

import emoji
import re

test_list=['? ? me así,bla es,se ? ds ???']

## Create the function to extract the emojis
def extract_emojis(a_list):
    emojis_list = map(lambda x: ''.join(x.split()), emoji.UNICODE_EMOJI.keys())
    r = re.compile('|'.join(re.escape(p) for p in emojis_list))
    aux=[' '.join(r.findall(s)) for s in a_list]
    return(aux)

## Execute the function
extract_emojis(test_list)

## the output
['? ? ? ? ? ?']

Answer #7:

Step 1: Make sure that your text it’s decoded on utf-8 text.decode('utf-8')

Step 2: Locate all emoji from your text, you must separate the text character by character [str for str in decode]

Step 3: Saves all emoji in a list [c for c in allchars if c in emoji.UNICODE_EMOJI] full example bellow:

>>> import emoji
>>> text     = "? ? me así, bla es se ? ds ???"
>>> decode   = text.decode('utf-8')
>>> allchars = [str for str in decode]
>>> list     = [c for c in allchars if c in emoji.UNICODE_EMOJI]
>>> print list
[u'U0001f914', u'U0001f648', u'U0001f60c', u'U0001f495', u'U0001f46d', u'U0001f459']

if you want to remove from text

>>> filtred  = [str for str in decode.split() if not any(i in str for i in list)]
>>> clean_text = ' '.join(filtred)
>>> print clean_text
me así, bla es se ds

Answer #8:

from emoji import *

EMOJI_SET = set()

# populate EMOJI_DICT
def pop_emoji_dict():
    for emoji in UNICODE_EMOJI:
        EMOJI_SET.add(emoji)

# check if emoji
def is_emoji(s):
    for letter in s:
        if letter in EMOJI_SET:
            return True
    return False

This is a better solution when working with large datasets since you dont have to loop through all emojis each time. Found this to give me better results 🙂
