python的re模块应用实例

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'
