如何在 python (netmiko) 中从循环中获取多个输出到外部

Question

我是蟒蛇的新手。我有使用 netmiko 在多个交换机上运行多个“显示命令”的代码，当一切都在循环中时它工作正常。但是当我想通过将其分配为变量并打印它来将多个“显示命令”的输出带到循环外时，只打印输出之一。S1 = {    'device_type': 'cisco_ios',    'ip': '192.168.0.56',    'username': 'admin',    'password': 'admin'    }S2= {    'device_type': 'cisco_ios',    'ip': '192.168.0.57',    'username': 'admin',    'password': 'admin'    }all_devices = [S1,S2]for devices in all_devices:    print("\nLogging into the switch...")    net_connect = ConnectHandler(**devices)    net_connect.enable()    cmd = ["show vlan brief", "\n","\n","show ip interface brief"]    for show in cmd:        output=net_connect.send_command(show)        y = outputprint(y)

Answer 1

尝试这个：

S1 = {

    'device_type': 'cisco_ios',

    'ip': '192.168.0.56',

    'username': 'admin',

    'password': 'admin'

    }

S2= {

    'device_type': 'cisco_ios',

    'ip': '192.168.0.57',

    'username': 'admin',

    'password': 'admin'

    }

all_devices = [S1,S2]

y = []

for devices in all_devices:

    print("\nLogging into the switch...")

    net_connect = ConnectHandler(**devices)

    net_connect.enable()

    cmd = ["show vlan brief", "\n","\n","show ip interface brief"]

    for show in cmd:

        output=net_connect.send_command(show)

        y.append(output)

for x in y:

    print(x)
