If it's on linux you can just redirect the screen output to a file:

python initialfile.py 1>stdout.txt 2>stderr.txt

or if you want standard out and standard error to go to the same file:

python initialfile.py 1>output.txt 2>output.txt

or if you don't want to see anything on standard error:

python initialfile.py 1>output.txt 2>/dev/null


As for windows, I'll test it now...

It turns out you can at least redirect the output to a file, I'm not
sure what it does with standard error or even if it exists or not.

python initialfile.py > output.txt

should work.


Hope it helps,

Cameron.
