Part I, Getting Started
See "Part I Exercises" in Chapter 3 for the exercises.
Interaction. Assuming Python s configured properly, the interaction should look something like the following (you can run this any way you like (in IDLE, from a shell prompt, and so on):
...copyright information lines...>>>
"Hello World!"'Hello World!' >>> # Use Ctrl-D or Ctrl-Z to exit, or close window
Programs. Your code (i.e., module) file module1.py and the operating system shell interactions should look like this:

Modules. The following interaction listing illustrates running a module file by importing it:
import module1Hello module world! >>>
