I use python's Tkinter.
I was able to display multiple calculators on the screen, but if I displayed four at the same time, this time the calculator was only displayed and I couldn't calculate numbers without typing. How can I improve it so that four calculators can be displayed and used at the same time?
Now I write four codes below and four calculators are displayed, but I can't use the calculator function at the same time.
You can display multiple calculators but you cannot use the calculator at the same time

Tkinter is not so detailed ...
If you want to create more than one, you should define a class.
If you want to create multiple top level windows, use the Toplevel component.
I tried to display 4 other than the root window.
All four exits when you close the root window.
Information on which window is processed is passed to the argument self.
