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。
