利用wmi模块获取PC信息

获取PC信息的步骤主要有:

（1）打开存储信息的文件;

（2）实例化WMI类，利用各函数获取硬件信息类的列表;

（3）遍历硬件信息类列表，获取硬件信息并写入存储文件。

 1 import wmi 
 2 hardware=open('Hardware.txt', 'w')
 3    
 4 w=wmi.WMI()
 5 
 6 hardware.write("cpu type，main frequency：
")
 7 for processor in w.Win32_Processor():
 8     hardware.write("Processor ID: %s" % processor.DeviceID)
 9     hardware.write("
Process Name: %s" % processor.Name.strip()+'

') 
10 hardware.write('Memory size：')
11 totalMemSize=0
12 for memModule in w.Win32_PhysicalMemory():
13     totalMemSize+=int(memModule.Capacity)
14     hardware.write("
Memory Capacity: %.2fMB" %((totalMemSize+1048575)/1048576)+'

') 
15 hardware.write('Hard disk usage：')
16 for disk in w.Win32_LogicalDisk (DriveType=3):
17     temp=disk.Caption+" %0.2f%% free" %(100.0 * int(disk.FreeSpace) / int(disk.Size))
18     hardware.write('
'+temp)
19     hardware.write('
') 
20 hardware.write('
IP and MAC：
')
21 for interface in w.Win32_NetworkAdapterConfiguration(IPEnabled=1):
22     hardware.write('Network card driver information：')
23     hardware.write(interface.Description+'
') 
24     hardware.write('Network card MAC address：')
25     hardware.write(interface.MACAddress+'
')
26     hardware.write('IP address：')
27     hardware.write(interface.IPAddress[0]+'
')
28     hardware.write('Network IP interface')
29     hardware.write(interface.IPAddress[1]+'
')
30 hardware.close()

最终可以在当前目录下得到一个包含硬件信息的文本文件。
