In Tkinter, Canvas class is used to create different shapes with the help of some functions which are defined under Canvas class. Any shape that Canvas class creates requires a canvas, so before creating any shapes a Canvas object is required and needs to be packed to the main window.

Canvas Methods for shapes: 
Canvas.create_oval(x1, y1, x2, y2, options = …): It is used to create a oval, pieslice and chord. 
Canvas.create_rectangle(x1, y1, x2, y2, options = …): It is used to create rectangle and square. 
Canvas.create_arc(x1, y1, x2, y2, options = …) This is used to create an arc. 
Canvas.create_polygon(coordinates, options = …) THis is used to create any valid shapes. 

We are using a class to show the working of functions that helps to creates different shapes.
Class parameters – 

Data members used: master, canvas
Member functions used: create() method
Widgets used: Canvas
Tkinter method used: 

Below is the Python code –


# Imports each and every method and class
# of module tkinter and tkinter.ttk
from tkinter import * from tkinter.ttk import * class Shape:
    def __init__(self, master = None):
        self.master = master
        # Calls create method of class Shape
    def create(self):
        # Creates a object of class canvas
        # with the help of this we can create different shapes
        self.canvas = Canvas(self.master)
        # Creates a circle of diameter 80
        self.canvas.create_oval(10, 10, 80, 80,
                            outline = "black", fill = "white",
                            width = 2)
        # Creates an ellipse with horizontal diameter
        # of 210 and vertical diameter of 80
        self.canvas.create_oval(110, 10, 210, 80,
                            outline = "red", fill = "green",
                            width = 2)
        # Creates a rectangle of 50x60 (heightxwidth)
        self.canvas.create_rectangle(230, 10, 290, 60,
                                outline = "black", fill = "blue",
                                width = 2)
        # Creates an arc of 210 deg
        self.canvas.create_arc(30, 200, 90, 100, start = 0,
                          extent = 210, outline = "green",
                          fill = "red", width = 2)
        points = [150, 100, 200, 120, 240, 180,
                  210, 200, 150, 150, 100, 200]
        # Creates a polygon
        self.canvas.create_polygon(points, outline = "blue",
                              fill = "orange", width = 2)
        # Pack the canvas to the main window and make it expandable
        self.canvas.pack(fill = BOTH, expand = 1)
if __name__ == "__main__":
    # object of class Tk, responsible for creating
    # a tkinter toplevel window
    master = Tk()
    shape = Shape(master)
    # Sets the title to Shapes
    # Sets the geometry and position
    # of window on the screen
    master.geometry("330x220 + 300 + 300")
    # Infinite loop breaks only by interrupt
