Hi. I started running the program in the terminal rather than IDLE. It

that when the program is finished running, it prints:

That is probably writing to stderr so you can redirect the stderr output
to a file (or /dev/null if you're feeling confident!)
$ python myprog.py myargs 2> myprog.err &
runs myprog.opy in the background and redirects stderr to the file
myprog.err. You can then open mpyprog.err in any text editor to read it
if you wish - hopefully it will be very boring!
And I can't access the data that the program returned. Do I need the
program to be saved to a text file, or is there a way to simply print it
out? It's a small amount of data, and I'd rather just print it out.
It should print to stdout so you can see it but in general its probably
better to redirect that to a file too... Especially if you have multiple
programs in one terminal! So your command lines should probably look like
$ python myprog.py myargs 2> myprog.err 1> myprog.out &
