[Tutor] regex advise + email validate

[Norman Khine]

hello, i have this code

http://pastie.org/1193091

i would like to extend this so that it validates TLD's such as .travel
and .museum, i can do this by changing {2,4} to {2,7} but this sort of
defeats the purpose of validating the correct email address.

are there any python libraries available to use for this?

thanks
