[Tutor] Newbie problems

[Dave Angel]

1) Please reply-list, or if your email program doesn't support that, do 
a reply-all.  The idea is to make sure tutor at python.org is in your To: 
field.  Otherwise you're just leaving private messages, and that's not 
what a public forum like this is about.

2) Please use text email, not html.  As you can see below, your 
formatting was thoroughly trashed by your email program.  I took a 
message at the html in your message, and you tried to use color as well, 
which won't be visible by most people here.

Your remaining problem is that green_numbers isn't a list or tuple, it's 
just a single number.  You can change either of the following ways:

green_numbers = (0,)      #The comma forces it to be a tuple
or
green_numbers = [0]       #it's a list

Alternatively, you could use == for green, and in for the other two. 
But as good programming practice, it's good to keep symmetry for the 3 
cases.
