I'm work on telegram bot, not the console, need to get the help content to send to user, rather than print out to console, something like this
parser = argparse.ArgumentParser()
parser.add_argument("-a", "--aaa", help="help for aaa")
cmd=["-a", "seta"]
args = parser.parse_args(cmd)
helpstring = parser.print_help() # get the help content for furthur process
telegrambot.send(helpstring)
