I am using 3.6.8 version of python.
I am seeing an error as AttributeError: 'Namespace' object has no attribute 'func' while using argparse . The code is working fine with python2.7 argparser.

I see a similar bug [4] reported at python 3.3 and  python3.4. The workaround mentioned works fine for a single level command.
 
Scenarios:
- If there is one command and various subcommands, like [1].The solution works fine.
- But suppose I have a command with mutiple level of subcommands like [2]. In this case if I give [3] as a command the ArgumentParser.prog() takes just the first command as input in this 
  case (open-stack). Hence the parser.print_usage prints [1].
