I'm having string like this:

❗foo-foo⚠ 9-8 ‍♀foo♀

Return of this example should be like this (separate):

❗ foo-foo ⚠ 9-8 ‍♀ foo ♀

regex_sws = re.compile(r"([A-zА-яёЁ0-9−\-‒–一—―─]+)([^A-zА-яёЁ0-9]+)([A-zА-яёЁ0-9−\-‒–一—―─]+)", re.MULTILINE)

but how to extract groups \1\2\3 ?

python regex

In the current emoji standard (see Emoji List, v13.1), there are 4590 emojis.

You need to use a regex that matches each separate emoji to re.split the string while keeping the emojis themselves, get rid of empty strings and join the resulting list with a single space:

import re
emoji_rx =

See the Python demo.

The fr'\s*({emoji_rx})\s*' part creates a regex that matches zero or more whitespaces, an emoji capturing it into Group 1, and then again zero or more whitespaces. Since the emoji is captured, it is not removed from the resulting list. Since there are consecutive matches, there can be empty matches in the resulting list, so these need removing, hence the list comprehension is used.
