Unfortunately, subprocess module doesn't allow it out-of-the-box, but you can use fnctl calls to perform non-blocking reads/writes on it's pipes, like this: flags = fcntl.fcntl(fd, fcntl.F_GETFL) fcntl.fcntl(fd, fcntl.F_SETFL, flags | os.O_NONBLOCK) After that, you can grab all the available data from the pipe at any given time w/o blocking.
