class Popen(builtins.object):

help(Popen)

Execute a child program in a new process.

For a complete description of the arguments see the Python documentation.

Arguments:
  args: A string, or a sequence of program arguments.

  bufsize: supplied as the buffering argument to the open() function when
      creating the stdin/stdout/stderr pipe file objects

  executable: A replacement program to execute.

  stdin, stdout and stderr: These specify the executed programs' standard
      input, standard output and standard error file handles, respectively.

  preexec_fn: (POSIX only) An object to be called in the child process
      just before the child is executed.

  close_fds: Controls closing or inheriting of file descriptors.

  shell: If true, the command will be executed through the shell.

  cwd: Sets the current directory before the child is executed.

  env: Defines the environment variables for the new process.

  text: If true, decode stdin, stdout and stderr using the given encoding
      (if set) or the system default otherwise.

  universal_newlines: Alias of text, provided for backwards compatibility.

  startupinfo and creationflags (Windows only)

  restore_signals (POSIX only)

  start_new_session (POSIX only)

  process_group (POSIX only)

  group (POSIX only)

  extra_groups (POSIX only)

  user (POSIX only)

  umask (POSIX only)

  pass_fds (POSIX only)

  encoding and errors: Text mode encoding and error handling to use for
      file objects stdin, stdout and stderr.

Attributes:
    stdin, stdout, stderr, pid, returncode
