Subprocess.popen() should write to log without waiting for process to complete

Here is my test code
Code:
            process = sp.Popen(['make'] + [os.path.expandvars(item)
                                           for item in make_line],
                               bufsize=1,
                               universal_newlines=True,
                               stdout=sp.PIPE, stderr=sp.STDOUT,
                               cwd=src_home)
            output, _ = process.communicate()
            inner_logger_console.info(str(output.strip()))

I am trying with bufsize=0 or 1 to get near to real-time output in the logs. What I have to do? process.communicate() has to go right?

NAME
GnuPG::Handles - GnuPG handles bundle SYNOPSIS
use IO::Handle; my ( $stdin, $stdout, $stderr, $status_fh, $logger_fh, $passphrase_fh, ) = ( IO::Handle->new(), IO::Handle->new(), IO::Handle->new(), IO::Handle->new(), IO::Handle->new(), IO::Handle->new(), ); my $handles = GnuPG::Handles->new ( stdin => $stdin, stdout => $stdout, stderr => $stderr, status => $status_fh, logger => $logger_fh, passphrase => $passphrase_fh, ); DESCRIPTION
GnuPG::Handles objects are generally instantiated to be used in conjunction with methods of objects of the class GnuPG::Interface. GnuPG::Handles objects represent a collection of handles that are used to communicate with GnuPG. OBJECT METHODS
Initialization Methods new( %initialization_args ) This methods creates a new object. The optional arguments are initialization of data members. hash_init( %args ). OBJECT DATA MEMBERS
stdin This handle is connected to the standard input of a GnuPG process. stdout This handle is connected to the standard output of a GnuPG process. stderr This handle is connected to the standard error of a GnuPG process. status This handle is connected to the status output handle of a GnuPG process. logger This handle is connected to the logger output handle of a GnuPG process. passphrase This handle is connected to the passphrase input handle of a GnuPG process. command This handle is connected to the command input handle of a GnuPG process. options This is a hash of hashrefs of settings pertaining to the handles in this object. The outer-level hash is keyed by the names of the handle the setting is for, while the inner is keyed by the setting being referenced. For example, to set the setting "direct" to true for the filehandle "stdin", the following code will do: # assuming $handles is an already-created # GnuPG::Handles object, this sets all # options for the filehandle stdin in one blow, # clearing out all others $handles->options( 'stdin', { direct => 1 } ); # this is useful to just make one change # to the set of options for a handle $handles->options( 'stdin' )->{direct} = 1; # and to get the setting... $setting = $handles->options( 'stdin' )->{direct}; # and to clear the settings for stdin $handles->options( 'stdin', {} ); The currently-used settings are as follows: direct If the setting "direct" is true for a handle, the GnuPG process spawned will access the handle directly. This is useful for having the GnuPG process read or write directly to or from an already-opened file. SEE ALSO
