本文实例讲述了Python实现的读取电脑硬件信息功能。分享给大家供大家参考，具体如下：

上学那会，老师让我用java获取电脑硬件信息，CPU, 硬盘，MAC等，那个时候感觉搞了好久。。。。。。

今天，用python试了一下，简单多了。分享一下：

首先安装wmi库，wmi是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。大多用户习惯于使用众多的图形化管理工 具来管理Windows资源，在wmi之前这些工具都是通过 Win32应用程序编程接口来访问和管理Windows资源的。大多数脚本 语言都不能直接调用Win32 API，wmiI的出现使得系统管理员可以通过一种简便的方法即利用常见的脚本语言实现常用的系统管理任务。好了，上代码吧

import wmi
import time
import json
import win32com
class PCHardwork(object):
 global s
 s = wmi.WMI()
 def get_CPU_info(self):
  cpu = []
  cp = s.Win32_Processor()
  for u in cp:
   cpu.append(
    {
     "Name": u.Name,
     "Serial Number": u.ProcessorId,
     "CoreNum": u.NumberOfCores,
     "numOfLogicalProcessors": u.NumberOfLogicalProcessors,
     "timestamp": time.strftime('%a, %d %b %Y %H:%M:%S', time.localtime()),
     "cpuPercent": u.loadPercentage
    }
   )
  print ":::CPU info:", json.dumps(cpu, True, indent=4)
  return cpu
 def get_disk_info(self):
  disk = []
  for pd in s.Win32_DiskDrive():
   disk.append(
    { 
     "Serial": s.Win32_PhysicalMedia()[0].SerialNumber.lstrip().rstrip(), # 获取硬盘序列号，调用另外一个win32 API
     "ID": 123456,
     "Caption": pd.Caption,
     "size": str(int(float(pd.Size)/1024/1024/1024))+"G"
    }
   )
  print":::Disk info:", json.dumps(disk, True, indent=4)
  return disk
 def get_network_info(self):
  network = []
  for nw in s.Win32_NetworkAdapterConfiguration (IPEnabled=1):
   network.append(
    {
     "MAC": nw.MACAddress,
     "ip": nw.IPAddress
    }
   )
  print":::Network info:", json.dumps(network, True, indent=4)
  return network
 def get_running_process(self):
  process = []
  for p in s.Win32_Process():
   process.append(
    {
     p.Name: p.ProcessId
    }
   )
  print":::Running process:", json.dumps(process, True, indent=4)
  return process
#运行测试：
PCinfo = PCHardwork()
PCinfo.get_CPU_info()
PCinfo.get_disk_info()
PCinfo.get_network_info()
PCinfo.get_running_process()

运行结果：

简单吧，附上wmi api说明: https://msdn.microsoft.com/en-us/library/bg126473%28v=vs.85%29.aspx

补充：这里使用Python2.7平台测试，可能会出现如下错误：

1. no module named wmi 错误

可使用pip命令解决：

pip install wmi

即可。

2. no module named win32com.client 错误

本站下载pywin32-223-cp27-none-win32.whl 。

使用如下命令安装：

pip install pywin32-223-cp27-none-win32.whl

即可。
