WMI (Windows Management Instrumentation) 模块可用于获取 Windows 内部信息，在使用Python获取Windows系统上的相关的信息可以使用WMI接口来获取，

什么是wmi？

WMI是一项核心的Windows管理技术，WMI作为一种规范和基础结构，通过它可以访问、配置、管理和监视几乎所有的Windows资源，比如用户可以在远程计算机器上启动一个进程；设定一个在特定日期和时间运行的进程；远程启动计算机；获得本地或远程计算机的已安装程序列表；查询本地或远程计算机的Windows事件日志等等。

该模块需要 win32com 的支持，环境安装如下，

pip install wmi

pip install pypiwin32

测试安装结果

>>> import win32con

>>> import wmi

导入模块没有报错，证明安装完成

wmi.WMI() 用于生成wmi实例
>>> wmi.WMI()

<_wmi_namespace: <COMObject winmgmts:>>

查询CPU信息

用于获取CPU处理器信息对象，并存以列表形式

wmi.Win32_Processor() 方法

返回参数: processorList

processorList: list类型，list中每个元素均为一个含cpu信息的object对象

import wmi

w = wmi.WMI()

cpu_list = w.Win32_Processor()

print(cpu_list)

# [<_wmi_object: b'\\\\QH-20181120YSCF\\root\\cimv2:Win32_Processor.DeviceID="CPU0"'>]
