Python + cmd/bash script question

[flyingsliverfin]

I'm trying to figure out how to get python to run a script (in either windows cmd or ubuntu bash), and then enter some things into the prompts. I can get python to run the scripts easily, but I don't know how to pipe input into the program once they are running...

Not sure if that's very clear, let me know if you need futher clarifications

thanks

I've never tried it but there's an 'expect' module you could try
