Thanks for you help,
Another question, is there a way of comparing two regexs?
EG
s1='st*r'
s2='s*ar'
r1=s1.replace('*','.*')
r2=s2.replace('*','.*')
re.match(r1,r2)?
=============
Also how do I use <_sre.SRE_Match object at 0x00E3F6B0> in my program?
If its a match, I want to be able to return 'true' or 1
