How to make bash complete only working on exact position, then back to normal

For example, I have a python script "control_center.py" which takes the $1 (start stop reboot) as command, and extra options (-a foo/bar).

control_center.py [start|stop|reboot] -a [foo|bar]  

I have used argcomplete, it works fine with the options.

cotrol_center.py start -a <tap> <tap>  bar foo  

However, the argcomplete can not auto fills the command (start|stop|reboot) for me.

I've tried to edit one bash complete script my self, it does can gives me the hint on the first argument, but it disabled the argcomplete at the same time.

control_center.py <tap> <tap>  start stop reboot  control_center.py start -a <tap> <tap>  # nothing pops out  

What I want is something like below:

control_center.py <tap> <tap>  start stop reboot  control_center.py start -a <tap> <tap>  bar foo  

Btw, here is my auto completion bash script.

#!/usr/bin/env bash  _control_center_completions()  {    if [ "${#COMP_WORDS[@]}" != "2" ]; then      return    fi      COMPREPLY=($(compgen -W "start stop reboot" -- "${COMP_WORDS[1]}"))  }    complete -F _control_center_completions control_center.py  

I wonder if I can do some modification on that script so the argcomplete won't be disabled.
