no.

did you read james strouds reply to your earlier post?  the behaviour
you're describing is exactly what Python's supposed to do if you type
commands into the interactive command-line prompt.

if you don't want the Python interpreter to execute each command as
you type it, you need to use a text editor (notepad, idle, ...) and save
the entire text to a file *before* you run it.

all this is described in chapter 1 of the book you're reading:

     "There are two ways to use the interpreter: command-line mode
    and script mode. In command-line mode, you type Python programs
    and the interpreter prints the result /.../

    Alternatively, you can write a program in a file and use the interpreter
    to execute the contents of the file. Such a file is called a script. /.../"

here's an IDLE tutorial that shows you how to use both the command-line
mode and and the script mode:

hope this helps!
