Subparser function calls

Question

How do I call the following functions below based on user input?

For example, if they type:

python test.py cmd1 -n hostname

• it will call def cmd1 and pass the -n parameter (hostname) to function

  import argparse
  
  def cmd1(node):
    print('cmd1')
  
  def cmd1_option1():
    print('cmd2')
  
  def cmd1_option1(template):
    print('cmd3')
  
  
  parser = argparse.ArgumentParser()
  subparsers = parser.add_subparsers(help='Functions')
  command_1 = subparsers.add_parser('cmd1', help='...')
  command_1.add_argument('-n', "--node", type=str, help='...')
  
  command_2 = subparsers.add_parser('cmd2', help='...')
  
  command_3 = subparsers.add_parser('cmd3', help='...')
  command_3.add_argument('-t', "--template", type=int, help='...')
  
  args = parser.parse_args()
