Thanks a lot pyTony.....it is very useful.....only one doubt,

pattern = "[\.\w]{2,}[@]\w+[.]\w+"

In this syntax i understand everything, just a doubt in [\.\w] the first one \w u used for the alphanumeric character if i am not wrong, but why you used \. before that... if you could explain me here, it will be very helpful..

I did not do that regexp, somebody else suggested it and I showed it did not work so well in comparision to my Python function. \. Is used in regexp to signify regular point instead of any character.
