从Python WMI获取CPU信息

Question

我正在尝试通过Python的WMI模块获取一些系统信息，但网上提到的很多方法似乎都不管用。我知道用其他语言做这件事会简单一些，但我想尝试用Python来实现，出于某些原因。

我试过使用Win32_TemperatureProbe()这个方法，但返回值是None。我也试过MSAcpi_ThermalZoneTemperature()，但出现了下面的错误。我一直在研究这个问题，但似乎找不到其他的方法或解决这些错误的办法。虽然有很多相关的讨论，但没有一个能解决问题。

这是我目前的代码：

import wmi, platform

#Initiating WMI
c = wmi.WMI(namespace="root\\wmi")

#Setting variables
drive_letter, free_space = [], []
stats = {}

#Getting basic infromation
print(platform.processor())
print(c.MSAcpi_ThermalZoneTemperature()[0].CurrentTemperature/10.0)-273.15

for disk in c.Win32_LogicalDisk(["Caption","FreeSpace"], DriveType=3):
   free_space_GB = round(int((disk.FreeSpace))/1073741824, 2)
   drive_letter.append(str(disk.Caption))
   free_space.append(str(free_space_GB))

stats = {"Free Space":free_space, "Drive Letter":drive_letter}

print(stats)

这是我运行这段代码时得到的输出：

During handling of the above exception, another exception occurred:

当我把命名空间改为null时，错误变成了这个：

    raise AttributeError("%s.%s" % (self._username_, attr))

这个方法有没有解决办法，或者有没有其他可行的替代方案？还是我应该干脆放弃，去专注于其他语言呢？
