How to find out Chinese or Japanese Character in a String in Python?

Question

Add () to Chinese and Japanese Characters:

Answer 1

You can do the edit using the regex package, which supports checking the Unicode "Script" property of each character and is a drop-in replacement for the re package:

import regex as re

pattern = re.compile(r'([\p{IsHan}\p{IsBopo}\p{IsHira}\p{IsKatakana}]+)', re.UNICODE)

input = u'sdf344asfasf天地方益3権sdfsdf'
output = pattern.sub(r'(\1)', input)
print output  # Prints: sdf344asfasf(天地方益)3(権)sdfsdf

You should adjust the \p{Is...} sequences with the character scripts/blocks that you consider to be "Chinese or Japanese".
