Reading piped output line by line python

Question

I'm using popen to run a subprocess in python. I need to read each line the subprocess outputs as it is being outputted, rather then getting everything once the process terminates. I've tried everything I could find on Google with no success. Any help would be greatly appreciated.

The subprocess.Popen documentation describes the available arguments to its call.

You want to set the bufsize argument to 1 (line-buffered input/output).
