如何在python（netmiko）中从循环中获取多个输出到外部

Question

我是 python 的新手。我有代码可以使用 netmiko 在多个交换机上运行多个“显示命令”，当一切都在循环中时，它工作正常。但是，当我想通过将多个“显示命令”的输出分配为变量并将其打印在循环外时，只打印其中一个输出。

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 = output

print(y)

试试这个：

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)
