To make sure that you can interact with IDLE, try the following steps on your computer:
• Start IDLE. To do this in Windows, click the Start button, then All Programs. In the Python program group click IDLE (Python GUI).
• When IDLE starts, it should appear similar to the window previously shown in Figure 1-21. At the >>> prompt type the following statement and then press Enter:
                   print('This is a test of IDLE.') enter
• After pressing the Enter key the Python interpreter will execute the statement. If you typed everything correctly, your session should look like this:
 >>>print('This is a test of IDLE.') enter
This is a test of IDLE.
>>>
• If you see an error message, enter the statement again and make sure you type it exactly as shown.
• Exit IDLE by clicking File, then Exit (or pressing Ctrl-Q on the keyboard).
