【问题描述】：
我试图通过 python 获取有关计算机的所有信息，但没有好的库可以找到显示器或键盘或图形卡的详细信息。
是否可以获取计算机的硬件或设备列表？

【问题描述】：
我个人觉得 psutil 库对于监视系统上正在发生的一切很有趣：
https://github.com/giampaolo/psutil
此外，您可能会查看平台库，您可以使用它来收集信息，猜猜是什么平台，是的。
https://docs.python.org/2/library/platform.html
如果您在 linux 上，使用 lspci 和朋友等系统命令来收集其他信息可能是一种解决方案。例如，请参阅：http://www.commandlinefu.com/commands/using/lspci
还有一个关于堆栈溢出的类似问题：Python, In linux obtain VGA specifications via lspci or HAL?

您可以使用psutil。这是我很久以前在 Python 2.7 中创建的一个很好的例子：

time = datetime.datetime.now().strftime("%I:%M:%S %p")
date = datetime.datetime.now().strftime("%Y-%m-%d")

e13 = Entry(master)
e13.grid(row=16, column=1)
e13.insert(10, time)
Label(master, text="System Date").grid(row=17, columnspan=2, sticky='w')
e14 = Entry(master)
e14.grid(row=17, column=1)
