[Tutor] REGEX EXPLANATION

[Luke Paireepinart]

Which part of the regexes do you not understand? Have you tried
figuring themselves out yourself first?
We don't typically give out answers here.  This is a tutor list, not a
solve your problems for you list.  We're here to teach you how to
fish, not cook for you.  So show us where you're stuck and we'll help
out.

Did you read the Python regex documentation online? I find it's quite
good.  Should give you a push in the right direction.
