## Overview

The article shows how to draw circles on canvas of the application body in Python. Ellipse function can be used for drawing circle, but arguments are not very user friendly. So you can write this new function for drawing a circle easier. Here is a function that will draw yellow circle with black outline.

## Code

`# from appuifw import *# c = Canvas()# app.body = c def circle(x,y,radius=5, outline=0, fill=0xffff00, width=1):  c.ellipse((x-radius, y-radius, x+radius, y+radius), outline, fill, width)`

You may use other default values.

Here's an example using this new circle function to show circles randomly

`# import required modulesimport e32from random import randint, choicefrom appuifw import * # Define exit functiondef quit():    App_lock.signal()app.exit_key_handler = quit app.screen = 'large' # Screen size set to 'large'c = Canvas()app.body = c sleep = e32.ao_sleepcolors = [0xff0000, 0x00ff00, 0x0000ff, 0xffff00, 0xffffff] # Function which draws circle with given radius at given co-ordinatedef circle(x,y,radius=5, outline=0, fill=0xffff00, width=1):  c.ellipse((x-radius, y-radius, x+radius, y+radius), outline, fill, width)  def rand_circle(n):  c.clear()  for i in range(n):    circle(randint(0,250), randint(0,180), randint(5,20), fill=choice(colors))    sleep(0.1) # Draw 40 circlesrand_circle(40) App_lock = e32.Ao_lock()App_lock.wait()  # Wait for exit event`
