It sounds like maybe you are using a "highlighting" text editor. That means
the text editor adds color depending on the syntax of the colored text.
For instance, if you have
print "Game Over"
in the editor, the word "print" might be blue because it is a python keyword
and the "Game Over" might be orange because it is a string.
It is also possible that the book is doing something similar and coloring
the different words to show more information about their purpose or meaning.
If you then run that program in the normal text terminal it would just print
out in whatever color the terminal happens to be (in my case green text on
a black background).
If you want to make the text a particular color, you would need to tell python
how to change the color, and that is going to take some more work.
You may want to join the tutor mailing list which is set up specifically to
help people who are brand new to python and/or programming.
