使用Python获取CPU、内存和硬盘等windowns系统信息的2个例子

例子一：

Python用WMI模块获取windowns系统的硬件信息：硬盘分区、使用情况，内存大小，CPU型号，当前运行的进程，自启动程序及位置，系统的版本等信息。

代码如下:
#!/usr/bin/env python
# -*- coding: utf-8 -*-

import wmi
import os
import sys
import platform
import time

def sys_version(): 
    c = wmi.WMI ()
    #获取操作系统版本
    for sys in c.Win32_OperatingSystem():
        print "Version:%s" % sys.Caption.encode("UTF8"),"Vernum:%s" % sys.BuildNumber
        print  sys.OSArchitecture.encode("UTF8")#系统是32位还是64位的
        print sys.NumberOfProcesses #当前系统运行的进程总数

def cpu_mem():
    c = wmi.WMI ()       
    #CPU类型和内存
    for processor in c.Win32_Processor():
        #print "Processor ID: %s" % processor.DeviceID
        print "Process Name: %s" % processor.Name.strip()
    for Memory in c.Win32_PhysicalMemory():
        print "Memory Capacity: %.fMB" %(int(Memory.Capacity)/1048576)

def cpu_use():
    #5s取一次CPU的使用率
    c = wmi.WMI()
    while True:
        for cpu in c.Win32_Processor():
             timestamp = time.strftime('%a, %d %b %Y %H:%M:%S', time.localtime())
             print '%s | Utilization: %s: %d %%' % (timestamp, cpu.DeviceID, cpu.LoadPercentage)
             time.sleep(5)    

def disk():
    c = wmi.WMI ()   
    #获取硬盘分区
    for physical_disk in c.Win32_DiskDrive ():
        for partition in physical_disk.associators ("Win32_DiskDriveToDiskPartition"):
            for logical_disk in partition.associators ("Win32_LogicalDiskToPartition"):
                print physical_disk.Caption.encode("UTF8"), partition.Caption.encode("UTF8"), logical_disk.Caption

    #获取硬盘使用百分情况
    for disk in c.Win32_LogicalDisk (DriveType=3):
        print disk.Caption, "%0.2f%% free" % (100.0 * long (disk.FreeSpace) / long (disk.Size))

def network():
    c = wmi.WMI ()
