Python通过命令参数传递IP列表：端口[重复]答案

【问题描述】：

我正在尝试通过一个名为 HOSTS 的变量的命令参数解析 IP:ports 列表，以在函数中使用 - read_head_block_ints。

parser = argparse.ArgumentParser(description='chain info checker')
parser.add_argument('host', help='host address')
parser.add_argument('function', help='check to run', choices=ALLOWED_FUNCTIONS)
parser.add_argument('--hosts', dest='HOSTS', type=list)

def read_head_block_ints():
    for host in HOSTS:
        try:
            data = requests.get(URLS['get_info'].format(host=host), verify=False).json()  # returns data in JSON format
            HEAD_BLOCK_INTS.append(float(data['head_block_num']))   # this is the head_block INT
        except:
            print('Error cannot connect to host {host}'.format(host=host))

当我使用--hosts 1.2.3.4:888 5.6.7.8:8888 9.9.9.9:8888 调用脚本时

我收到以下error: unrecognized arguments: 5.6.7.8:8888 9.9.9.9:8888

把验证设为真
