Getting computer hardware information - python

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:

So this seems like a simple issue but let me know if I misunderstood. What you want to do is disable and enable a text widget. To do this you would use some_text_widget.config(state="enabled") to enable the widget and/or some_text_widget.config(state="disabled"). Does this work for you?

How to Make Plot Show up?

Any help would be appreciated, thank you!
You're passing funcPlot as the command for Scale to call:
mscale = tk.Scale(root1, ..., command=funcPlot)
According to the documentation, command is:
A procedure to be called every time the slider is moved. This
procedure will be passed one argument, the new scale value.
But instead of taking one argument, your funcPlot() function requires six arguments:
def funcPlot(input_list, mscale, bscale, kscale, a, canvas, event=None):
Which leads to the error:
TypeError: funcPlot() missing 5 required positional arguments: 'mscale', 'bscale', 'kscale', 'a', and 'canvas'
You need to rethink how this is supposed to work. Below is my rework of your code. I got around the problem above by using global variables -- I'm not proud of that. I also had to rework the way your plot gets embedded in Tk as what you had wasn't working:

Can you help me with the problem?
Thanks in advance!!
Sorry for a long code. Anyways,the there are only input widgets and calculations.
As suggested by #PM 2Ring, you should consider adding a default value to the Entry element represented by body_weight. You can use the insert method to do this after creating body_weight.
See here.
Ive cleaned up your code a little bit and I've added an error handling statement for your float conversion problem. One thing you might consider doing is finding the formula for BAC calculations that utilizes kilograms instead of converting it to pounds. Also I would recommend looking up the PEP8 style guides. It helps keep code readable. Hope this helps :)
