python的re模块应用实例

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：

<type '_sre.SRE_Match'>foofoonot matchlovefoo|...|bat|search|bat

希望本文所述对大家的Python程序设计有所帮助。
