Question

Design the Python GUI to display the temperature & humidity on two gauges.

- Use the Tkinter Canvas Widget.

- The gauge should be in a separate file and can be integrated using the import directive.

- The gauge should have at least two parameters; e.g. the range (scale: min-max) and the fill color of the moving arc. You are free to add more.

You have to design the gauge and not import it
