Many programs behave differently when they're connected to an actual TTY compared to being connected to a pipe. What you often need to do is use a pseudo-terminal, which you can then feed stuff to and capture stuff from. Python makes this available with the pty module: https://docs.python.org/3/library/pty.html https://docs.python.org/2/library/pty.html (I would strongly recommend using Python 3 rather than Python 2, but it should be possible to do either way.)
