The doc looks clear to me. poll() returns the returncode attribute which is described thusly: "A None value indicates that the process hasn’t terminated yet." Therefore, I don't understand the confusion. poll() is explicitly non-blocking, and it is silly to expect it to return a process return code when the process hasn't returned yet (!). The correct answer is to use the wait() method (or communicate()), which is described two lines below poll(). May I suggest your colleagues didn't read the doc at all?
