helloworld.
py in IDLE
This tells the operating system to run Python and then load the
helloworld.py
file for
execution. Unlike the Python shell in IDLE, Python will quit when it reaches the end of the
file and return you to the terminal. The result, however, is the same: the message
Hello,
World!
is printed to the standard output (see Figure 12-4).
