for item in gcblist:  
    print (item)  
    print (item['device'])

在 Python 中，您应该使用 True 和 False 作为 bool 值的 true 和 false:

gcblist =[
{
    "band": "5",
    "channel": 155,
    "clients": 0,
    "country": "United States",
    "device": "wlan0",
    "enabled": True,
    "fbo": False,
    "fbo_active": False,
    "name": "5.0GHz",
    "ssids": [
        "TestWiFi"
    ],
    "txpower": "30"
},
{
    "band": "2.4",
    "channel": 1,
    "clients": 0,
    "country": "United States",
    "device": "wlan1",
    "enabled": True,
    "fbo": True,
    "fbo_active": False,
    "name": "2.4GHz",
    "ssids": [
        "TestWiFi"
    ],
    "txpower": "30"
}
