import re

bt = 'bat|bet|bit'
m = re.match(bt,'bat')
if m is not None:
    print m.group()
print '1>>>>>>>>>>>>>>'


m = re.match(bt,'blt')
if m is not None:
    print m.group()
print '2>>>>>>>>>>>>>>'


m = re.match(bt,'He bit me!')
if m is not None:
    print m.group()
print '3>>>>>>>>>>>>>>'


m = re.search(bt,'He bit me!')
if m is not None:
    print m.group()
print '4>>>>>>>>>>>>>>'

输出：

bat
1>>>>>>>>>>>>>>
2>>>>>>>>>>>>>>
3>>>>>>>>>>>>>>
