I have a question regarding extracting parts of a string and the meaning of # and % in the syntax. I created an example below.
In both of these examples , I wanted to: extract only the fourth part of the string and extract everything but the fourth part of the string, which I did successfully. Conceptually, I wanted to know what is the difference between # and % and why do I need ## in the first example as opposed to just #. Why cannot I use # instead of %? Thanks.
