python获取电脑硬件CPU/磁盘/BIOS特征信息

一、获取CPU信息

    def get_cpu_info(self):
        tmpdict = {}
        tmpdict["CpuCores"] = 0
        c = wmi.WMI()
        #          print c.Win32_Processor().['ProcessorId']
        #          print c.Win32_DiskDrive()
        for cpu in c.Win32_Processor():
            # print cpu
            print("cpu id:", cpu.ProcessorId.strip())
            tmpdict["CpuType"] = cpu.Name
            try:
                tmpdict["CpuCores"] = cpu.NumberOfCores
            except:
                tmpdict["CpuCores"] += 1
                tmpdict["CpuClock"] = cpu.MaxClockSpeed
                return tmpdict

二、获取CPU使用负载

    def read_cpu_usage(self):
        c = wmi.WMI()
        for cpu in c.Win32_Processor():
            return cpu.LoadPercentage

三、获取CPU/磁盘/BIOS序列号

    def get_disk_info(self):
        tmplist = []
        encrypt_str = ""
        c = wmi.WMI()
        for cpu in c.Win32_Processor():
            # cpu 序列号
            encrypt_str = encrypt_str + cpu.ProcessorId.strip()
            print("cpu id:", cpu.ProcessorId.strip())
        for physical_disk in c.Win32_DiskDrive():
            encrypt_str = encrypt_str + physical_disk.SerialNumber.strip()

            # 硬盘序列号
            print('disk id:', physical_disk.SerialNumber.strip())
            tmpdict = {}
            tmpdict["Caption"] = physical_disk.Caption
            tmpdict["Size"] = int(physical_disk.Size) / 1000 / 1000 / 1000
            tmplist.append(tmpdict)
        for board_id in c.Win32_BaseBoard():
            # 主板序列号
            encrypt_str = encrypt_str + board_id.SerialNumber.strip()
            print("main board id:", board_id.SerialNumber.strip())
        # for mac in c.Win32_NetworkAdapter():

        # mac 地址（包括虚拟机的）
        # print "mac addr:", mac.MACAddress:
        for bios_id in c.Win32_BIOS():
            # bios 序列号
            encrypt_str = encrypt_str + bios_id.SerialNumber.strip()
            print("bios number:", bios_id.SerialNumber.strip())
        print("encrypt_str:", encrypt_str)

        return encrypt_str

四、获取获取磁盘序列号信息，返回值类似：185224465301

    def get_HardDiskNumber(self):
        """
        获取磁盘序列号信息，返回值类似：185224465301
        :return: 
        """
        print('\n------   get HardDiskNumber  ------')
        import wmi
        c = wmi.WMI()
        for physical_disk in c.Win32_DiskDrive():
            physical_disk_sn=physical_disk.SerialNumber
            print('get_HardDiskNumber=',physical_disk_sn)
            return physical_disk_sn
