I wrote this simple script in Python:

import os
os.system("ping www.google.com")

It's working in interactive mode from cmd of windows, but seems it doesn't work if I write on IDLE (it appear a cmd black screen). This is the first problem.

The second thing that I like to do is this: I'd like to save the results of the pings in a file How can I do it?

I'm novice of Python (two days) ;) Thanks a lot.

    You can't do it with `os.system`. That's why [the docs for `os.system`](https://docs.python.org/3/library/os.html#os.system) specifically say, "The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the [*Replacing Older Functions with the subprocess Module*](https://docs.python.org/3/library/subprocess.html#subprocess-replacements) section in the `subprocess` documentation for some helpful recipes." – abarnert Sep 08 '14 at 11:08

you save the output using subprocess.check_output 

    import subprocess
    with open('output.txt','w') as out:
        out.write(subprocess.check_output("ping www.google.com"))

output.txt
