I'm sorry. Are you really serious? You don't know which is better: the one 
that is clean and readable, or the one that is obscure and doesn't work.

You re.match won't work if s1 contains any characters that have special 
meaning in regular expressions. There is an easy way around that, but I'm 
not going to tell you what it is.

For a case insensitive comparison simply do what you did first time around.
