python的re模組應用執行個體

本文執行個體講述了python的re模組應用。是非常重要的應用技巧。分享給大家供大家參考。

具體方法如下：

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從頭開始匹配   match_object = re.match('foo','afooabv') if match_object is not None:   print match_object.group() else:   print 'not match'    #利用物件導向的特點，一行完成 print re.match('love','lovesomebody is a happy thing').group()  #與match的區別：match從頭開始匹配，search是尋找 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()#會匹配成功 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()#會匹配成功，如果用match就不會匹配成功 else:   print 'not match' 

本文執行個體測試環境為Python2.7.6

運行結果如下：

foofoonot matchlovefoo|...|bat|search|bat

希望本文所述對大家的Python程式設計有所協助。
