Erase Empty Lines From List

Recommended Posts

Hey all,

I'm up against the proverbial 'wall'.

I have a variable that has a list of values. Some values have data, some do not. For example

Apt 2C

Apt 4D

Apt 8H

etc. etc.

How can I effectively filter out all of the empty lines from this list, including those at the top and the bottom? I feel like this is really simple, but perhaps it isn't. It certainly has me going around in circles. Thanks in advance for any help, all!
