Inherited from object: __class__

init(self, args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, close_fds=False, shell=False, cwd=None, env=None, universal_newlines=False, startupinfo=None, creationflags=0)
(Constructor)

Create new Popen instance.

Overrides: object.__init__

_internal_poll(self, _deadstate=None, _waitpid=<built-in function waitpid>, _WNOHANG=1, _os_error=<type 'exceptions.OSError'>)

Check if child process has terminated. Returns returncode attribute.

This method is called by __del__, so it cannot reference anything outside of the local scope (nor can any methods it calls).

communicate(self, input=None)

Interact with process: Send data to stdin. Read data from stdout and stderr, until end-of-file is reached. Wait for process to terminate. The optional input argument should be a string to be sent to the child process, or None, if no data should be sent to the child.

communicate() returns a tuple (stdout, stderr).

wait(self)

Wait for child process to terminate. Returns returncode attribute.
