Description:
 def execute_command(self, args, parent_environ=None, **subprocess_kwargs):
 """Run a command within a resolved context. This applies the context to a python environ dict, then runs a subprocess in that namespace. This is not a fully configured subshell - shell-specific commands such as aliases will not be applied. To execute a command within a subshell instead, use execute_shell(). Warning: This runs a command in a configured environ dict only, not in a true shell. To do that, call `execute_shell` using the `command` keyword argument. Args: args: Command arguments, can be a string. parent_environ: Environment to interpret the context within, defaults to os.environ if None. subprocess_kwargs: Args to pass to subprocess.Popen. Returns: A subprocess.Popen object. Note: This does not alter the current python session. """
