OK, let me write a regular expression that matches Chinese

The code is as follows	Copy Code
#-*-Coding:utf-8-*- Import re def findpart (regex, text, name): Res=re.findall (regex, text) If Res: Print "There are%d%s parts:n"% (len (res), name) For R in Res: Print "T", R.encode ("UTF8") Print Text = "#who #helloworld#a Chinese x#" Usample=unicode (text, ' UTF8 ') Findpart (U "#[wu2e80-u9fff]+#", Usample, "Unicode Chinese")

Test Match Chinese

The code is as follows	Copy Code
Import re message = U ' heaven and Man in Oneness '. Encode (' UTF8 ') Print (Re.search (U ' person '. Encode (' UTF8 '), message). Group ())

Examples in interactive mode

code is as follows	copy code
>>> Import re       >>> s= ' Phone No. 010-87654321 '       >>>       >>> r= Re.compile (R ' (d+)-(d+) ')       >>> m=r.search (s)        >>> m        <_sre. Sre_match object at 0x010ee218> )
