问题
I tried to get all information about a computer by python but there is no good library to find something like monitor or keyboard or details of graphic card.
Is it possible to get list of hardware or devices of computers?

I personally find the psutil library interesting for monitoring everything that is going on on your system:
https://github.com/giampaolo/psutil
Moreover, you might have a look at the platform lib, which you can use to gather information, guess what, platform, yes.
https://docs.python.org/2/library/platform.html
If you're on linux, it might be a solution to use some system command like lspci and friends to gather other information as well. See, for instance this: http://www.commandlinefu.com/commands/using/lspci
There's also a similar question on stack overflow: Python, In linux obtain VGA specifications via lspci or HAL?

You can use psutil. Here is a good example that I have created long time ago in Python 2.7:
from Tkinter import *
import psutil
import datetime
from multiprocessing import cpu_count
def timeFunc():
time = datetime.datetime.now().strftime("%I:%M:%S %p")
date = datetime.datetime.now().strftime("%Y-%m-%d")
Label(master, text="System Time").grid(row=16, columnspan=2, sticky='w')
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)
e14.insert(10, date)
def secs2hours(secs):
mm, ss = divmod(secs, 60)
hh, mm = divmod(mm, 60)
return "%d:%02d:%02d (H:M:S)" % (hh, mm, ss)
def bat():
if not hasattr(psutil, "sensors_battery"):
# outputList.append("Platform not supported")
Label(master, text="Status").grid(row=10, columnspan=2, sticky='w')
e9 = Entry(master)
e9.grid(row=11, column=1)
e9.insert(10, "Platform not supported")
batt = psutil.sensors_battery()
if batt is None:
# outputList.append("No battery is installed")
Label(master, text="Status").grid(row=10, columnspan=2, sticky='w')
e9 = Entry(master)
e9.grid(row=11, column=1)
e9.insert(10, "No battery is installed")
# print("charge: %s%%" % round(batt.percent, 2))
if batt.power_plugged:
Label(master, text="Charge").grid(row=11, columnspan=2, sticky='w')

e9 = Entry(master)
e9.grid(row=11, column=1)
