python -并行运行多个子进程，但允许在bash命令失败时重试吗？

import subprocess
from concurrent.futures import ThreadPoolExecutor

    try:
        # 运行命令
        process = subprocess.Popen(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

            while retries < max_retries:
                stdout, stderr = executor.submit(run_command, command).result()
                if stderr:

    'command1',
    'command2',
    'command3',
    # ...

# 运行命令并获取结果
