I want to delete a last 2 points from the path when uav is moving. In ma_wiget.py there is

  map_widget.delete_all_path()

This code delete all of the path but I want delete just the last points from the path

When I try to write a funcation in subclass of tkintermapview but It does not bring me together to change and reach the class. After that I try to acsess to canvas_path for remove the point.I call the remove_position but there is erorr in remove becuse remove just take 1 parameter
