To make sure that you can interact with the Python interpreter, try the following steps on your computer:
• Start the Python interpreter in interactive mode.
• At the >>> prompt type the following statement and then press Enter:
        print('This is a test of the Python interpreter.') enter

• After pressing the Enter key the interpreter will execute the statement. If you typed everything correctly, your session should look like this:
 >>> print('This is a test of the Python interpreter.') enter
               This is a test of the Python interpreter.
>>>
• If you see an error message, enter the statement again and make sure you type it
exactly as shown.
• Exit the Python interpreter. (In Windows, press Ctrl-Z followed by Enter. On other
systems press Ctrl-D.)
