Try looking at os.popen3

You can do something like

stdin, stdout, stderr = os.popen3(command)
while not done:
	try:
		outputstr = stdout.readline()
		if outputstr == '':
			done = 1
		else:
			# do something with textview and outputstr
	except (IOError):
		# ignore interrupted system calls here otherwise
		done = 1

stdin.close()
stdout.close()
stderr.close()
