注意：这段代码需要wmi  和 系统 win32 扩展支持。

没安装库的要先下载安装，我装的是 WMI-1.4.6.win32 和 pywin32-218.win32-py2.7

还有，代码里面文件目录自己修改下咯。

# -*- coding:gb2312 -*-  
import wmi
hardware=file('F:\Python\Hardware.txt','w')
 
w=wmi.WMI()
hardware.write("cpu型号，主频：\n")
for processor in w.Win32_Processor():          
hardware.write("Processor ID: %s" % processor.DeviceID)
hardware.write("\nProcess Name: %s" % processor.Name.strip()+'\n\n')
hardware.write('内存大小：')
totalMemSize=0
for memModule in w.Win32_PhysicalMemory():   
totalMemSize+=int(memModule.Capacity)
hardware.write("\nMemory Capacity: %.2fMB" %((totalMemSize+1048575)/1048576)+'\n\n')
hardware.write('硬盘使用情况：')
for disk in w.Win32_LogicalDisk (DriveType=3):
temp=disk.Caption+" %0.2f%% free" %(100.0 * long (disk.FreeSpace) / long (disk.Size))
hardware.write('\n'+temp)
hardware.write('\n')
hardware.write('\n显示IP和MAC：\n')
for interface in w.Win32_NetworkAdapterConfiguration (IPEnabled=1):
hardware.write('网卡驱动信息：')
hardware.write(interface.Description+'\n')
hardware.write('网卡MAC地址：')
hardware.write(interface.MACAddress+'\n')
#for ip_address in interface.IPAddress:
hardware.write('IP地址：')
hardware.write(interface.IPAddress[0]+'\n')
hardware.write('外网IP接口')
hardware.write(interface.IPAddress[1]+'\n')
hardware.close()
