本文实例讲述了python的re模块应用。是非常重要的应用技巧。分享给大家供大家参考。

具体方法如下:

import re 
# 
match_object = re.match(\'foo\',\'foo\') 
if match_object is not None: 
  print type(match_object) 
  print match_object.group() 
 
# 
match_object = re.match(\'foo\',\'fooabv\') 
if match_object is not None: 
  print match_object.group() 
  
#match从头开始匹配   
match_object = re.match(\'foo\',\'afooabv\') 
if match_object is not None: 
  print match_object.group() 
else: 
  print \'not match\' 
   
#利用面向对象的特点,一行完成 
print re.match(\'love\',\'lovesomebody is a happy thing\').group() 
 
#与match的区别:match从头开始匹配,search是查找 
match_object = re.search(\'foo\',\'afooabv\') 
if match_object is not None: 
  print match_object.group() 
else: 
  print \'not match\' 
   
#|的使用 
bt = \'bat|bit|bot\' 
match_object = re.match(bt,\'batsdf\') 
if match_object is not None: 
  print \"|...|\" + match_object.group()#会匹配成功 
else: 
  print \'not match\' 
   
bt = \'bat|bit|bot\' 
match_object = re.search(bt,\'aabatsdf\') 
if match_object is not None: 
  print \"|search|\" + match_object.group()#会匹配成功,如果用match就不会匹配成功 
else: 
  print \'not match\' 

本文实例测试环境为Python2.7.6

运行结果如下:


foo
foo
not match
love
foo
|...|bat
|search|bat

希望本文所述对大家的Python程序设计有所帮助。
