Question

8. Assume that in a program, the following statement creates a Canvas widget and a it to the self.canvas variable: self.canvas tkinter.Canvas(self.main_window, width-200, height-200) Write statements that do the following: a) Draws a blue line from the Canvas widget's upper-left corner to its lower-right corner. The line should be 3 pixels wide. Draws a rectangle with a red outline and a black interior. The rectangle's corners should appear in the following locations on the Canvas: b) Upper-left: (50, 50) Upper-right: (100, 50) Lower-left: (50, 100) . Lower-right: (100, 100) radius should be 50. corner at (20, 20), and its lower-right corner at (180, 180). The arc should start at . c) Draws a green circle. The circle's center-point should be at (100, 100), and its d) Draws a blue-filled arc that is defined by a bounding rectangle with its upper-left 0 degrees, and extend for 90 degrees.

Solution (a)-->

import tkinter
class ShapeExample:
def __init__(self):
self.main_window = tkinter.Tk()
self.canvas = tkinter.Canvas(self.main_window,width=200, height=200)
self.canvas.create_line(0,0,200,200,width="3")
  
self.canvas.pack()
tkinter.mainloop()
shape = ShapeExample()
