python hello.py -o hello.out

I think you should be doing this:
python hello.py > hello.out
** EDIT ** An additional question was asked about stdin.
From the command-line you can do something like this:
python foo.py < in.txt > out.txt
Inside foo.py you need to make sure you are grabbing stdin from somewhere, so do something like this:
import fileinput
for line in fileinput.input():
print(line)
# do stuff with each line of input

how about if i want to change the standard input to the given file in the command line. Something like
python hello.py -i hello.in -o hello.out
idjaw
Try this and let me know if it works
python foo.py < in.txt > out.txt. I've edited my post to reflect the updates for this.Unless your script supports -o itself, I do not expect that flag to do anything. python does not have such an option, and if it did, you would have to put it before the name of your script so that it could be identified as an option to the interpreter instead of your script.
Here is a good article on how to redirect output in Windows: https://support.microsoft.com/en-us/kb/110930. Surprisingly, it is done the same was as in Linux, using the > character. Your example should be written as either
python hello.py > hello.out
or as
python hello.py > hello.out 2>&1
if you want to include standard error as well as standard output in your file.
