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
