Python Tkinter | Create different shapes using Canvas class

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:
Canvas.create_oval()
Canvas.create_rectangle()
Canvas.create_arc()
Canvas.create_polygon()
pack()
title()
geometry()

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 
        self.create() 
      
    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, resposible for creating 
    # a tkinter toplevel window 
    master = Tk() 
    shape = Shape(master) 
  
    # Sets the title to Shapes 
    master.title("Shapes") 
  
    # Sets the geometry and position 
    # of window on the screen 
    master.geometry("330x220 + 300 + 300") 
  
    # Infnite loop breaks only by interrupt 
    mainloop()
