Unfortunately I can't give a custom example at this moment, but you have a perfectly good stdin pipe that can be used in your subprocess Popen command. Just google how to use it in the meantime. You can write to stdin in the parent process and read from it in the child. It would be exactly like what you originally described with http.The child can block and wait on stdin until the parent sends something.
