[Tutor] importance of quotes ..

[Kevin Liang]

Hi all,
	I was just working on ch.6, exercise 2  of Learning Python.  I 
came to the point when I had copied word-for-word the answer to the question 
(or so I thought), yet it still refused to run properly.. then I looked carefully,
and noticed a *return* statement had '''' quotes instead of `````.  I changed
it , and it worked..  Now, I'm a little confused as to why this is so important..
I'm always bogged down on things like this.  thanks
