Emoji表情正則匹配

emoji表情其實就是四位的unicode

所以我們可以通過unicode來識別emoji表情

<U+1F300> - <U+1F5FF>      # symbols & pictographs
<U+1F600> - <U+1F64F>      # emoticons
<U+1F680> - <U+1F6FF>      # transport & map symbols
<U+2600>  - <U+2B55>       # other

 目標是要匹配文本兩個emoji表情中間的文字

例如

🔐testtest🔐

代碼： 

readline=['​🔐testtest🔐']
import re
pat=re.compile(u'['u'\U0001F300-\U0001F64F'u'\U0001F680-\U0001F6FF'u'\u2600-\u2B55]'+'(.*?)'+u'['u'\U0001F300-\U0001F64F'u'\U0001F680-\U0001F6FF'u'\u2600-\u2B55]', re.UNICODE)
for line in readline:
    print(pat.findall(line))

結果： 

testtest
