def getPnpDeviceInfo():
    c = wmi.WMI()
    wql = "SELECT * FROM Win32_PnPEntity WHERE Manufacturer != 'Microsoft' AND NOT PNPDeviceID LIKE 'ROOT\\%'"
    print ("All physical PNP devices")
    for J in c.query(wql):
    print(J)


此函数(查询)通常返回所有物理PNP设备,这是一个输出示例:

instance of Win32_PnPEntity
{
Caption = "ACPI Lid";
ClassGuid = "{4d36e97d-e325-11ce-bfc1-08002be10318}";
ConfigManagerErrorCode = 0;
ConfigManagerUserConfig = FALSE;
CreationClassName = "Win32_PnPEntity";
Description = "ACPI Lid";
DeviceID = "ACPI\\PNP0C0D\\2&DABA3FF&3";
HardwareID = {"ACPI\\PNP0C0D", "*PNP0C0D"};
Manufacturer = "(Standard system devices)";
Name = "ACPI Lid";
PNPDeviceID = "ACPI\\PNP0C0D\\2&DABA3FF&3";
Status = "OK";
SystemCreationClassName = "Win32_ComputerSystem";
SystemName = "SUSDUTTA-LAP";
};


问题是,如果我只想提取实例的“ PNPDeviceID”,如何在python中执行此操作而不更改WQL?

最佳答案

没关系,可以在WMI python doc中找到。 WQL将答案作为列表返回,并且存在工厂方法“ __getattr__(self,'attribute_name'_)”,该方法使用特定的属性名称返回了数据。
