| 1-4. | Interactive Execution. Start your Python interactive interpreter. You can invoke it by typing in its full pathname or just its name (python or python.exe) if you have installed its location in your search path. (You can use any version or implementation of Python that is convenient to you, e.g., command line, GUI/IDE, Jython, IronPython, or Stackless.) The startup screen should look like the ones depicted in this chapter. When you see the >>>, that means the interpreter is ready to accept your Python commands. Try entering the command for the famous Hello World! program by typing print 'Hello World!' (and press RETURN), then exit the interpreter. On Unix systems, ˆD will send the EOF signal to terminate the Python interpreter, and on DOS systems, the keypress is ˆZ. Exiting from windows in graphical user environments like the Macintosh, PythonWin or IDLE on Windows, or IDLE on Unix can be accomplished by simply closing their respective windows. |
| 1-5. | Scripting. As a follow-up to Exercise 1-4, create "Hello World!" as a Python script that does exactly the same thing as the interactive exercise above. If you are using the Unix system, try setting up the automatic startup line so that you can run the program without invoking the Python interpreter. |
| 1-6. | Scripting. Create a script that displays your name, age, favorite color, and a bit about you (background, interests, hobbies, etc.) to the screen using the print statement. |
