Instance Methods

__init__(self, args, bufsize=0, executable=None, stdin=None, stdout=None, stderr=None, preexec_fn=None, shell=False, cwd=None, env=None, universal_newlines=False)
Create new Popen instance.

__del__(self, sys=<module 'sys' (built-in)>)

source code

communicate(self, input=None)
Interact with process: Send data to stdin.

source code

poll(self)

source code

_get_handles(self, stdin, stdout, stderr)
Construct and return tupel with IO objects: p2cread, p2cwrite, c2pread, c2pwrite, errread, errwrite

Execute program (POSIX version)

source code

_handle_exitstatus(self, sts)

source code

_internal_poll(self, _deadstate=None)
Check if child process has terminated.

source code

wait(self)
Wait for child process to terminate.

source code

_communicate(self, input)

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

source code

Create new Popen instance.

Overrides: object.__init__

communicate(self, input=None)

source code

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).

_internal_poll(self, _deadstate=None)

source code

Check if child process has terminated. Returns returncode attribute.

wait(self)

source code

Wait for child process to terminate. Returns returncode attribute.
