If you take a look at the python language guide, and keep in mind
that the 'string' module is available through the '_' namespace
variable (eg: "_.string.split(somevar)"), you can do even fancier
things like find the character position of the '_' in the string
and copy out just the characters after it.

In general, you want to take a look at the Python documentation
(www.python.org) to learn how to compose complex 'if' statments.
