Question

import argparse

parser = argparse.ArgumentParser(formatter_class=argparse.RawTextHelpFormatter)
commands = parser.add_subparsers(title='Available Commands')

cmd1_parser = commands.add_parser('setup1', help="Setup Device 1")
cmd1_parser.add_argument('-f', "--freq", help="Frequency in (Hz)",  metavar='\b', type=int, required=True)
cmd1_parser.add_argument('-p', "--power", help="Power level in (dB)", metavar='\b', type=int, required=True)
cmd1_parser.add_argument('-c', "--current", help="Current (mA)",  metavar='\b', type=int, required=True)

cmd2_parser = commands.add_parser('setup2', help="Setup Device 2")
cmd2_parser.add_argument('-l', "--length", help="Length in meters",  metavar='\b', type=int, required=True)
cmd2_parser.add_argument('-b', "--breadth", help="Breadth in meters", metavar='\b', type=int, required=True)
cmd2_parser.add_argument('-w', "--width", help="Width in meters",  metavar='\b', type=int, required=True)

parser.print_help()
cmd1_parser.print_help()
cmd2_parser.print_help()

此帮助输出的结果：

usage: test2.py [-h] {setup1,setup2} ...

optional arguments:
  -h, --help       show this help message and exit

Available Commands:
  {setup1,setup2}
    setup1         Setup Device 1
    setup2         Setup Device 2
usage: test2.py setup1 [-h] -f -p -c

optional arguments:
  -h, --help         show this help message and exit
  -f, --freq     Frequency in (Hz)
  -, --power    Power level in (dB)
  -c, --current  Current (mA)
usage: test2.py setup2 [-h] -l -b -w

optional arguments:
  -h, --help         show this help message and exit
  -l, --length   Length in meters
  -, --breadth  Breadth in meters
  -w, --width    Width in meters

在帮助输出中的可用命令：之后，请帮助我摆脱 {setup1，setup2} 行。基本上，我想抑制这种情况，因为命令列表已经显示。
