Code and Challenge

Copy and paste the code below. Run it! Read the task and see if you can do it before moving on to the next challenge

#NOTE: don't worry for now about the error that arises on closing the window
"""
==========Task===============
Type this out at the end of your program.
A main loop is basically the central part of your program that controls what the program does!
If you call the program from outside of IDLE, it will appear for a second and then disappear
To stop this from happening....we create in our main loop a little code, that tells tkinter to redraw the screen
.....the loop keeps running forever - until we close the window.

from tkinter import *
import random
import time

class Ball: #create a ball class
    def __init__(self,canvas,color): #initiliased with the variables/attributes self, canvas, and color
        self.canvas=canvas #set the intiial values for the starting attributes
        self.id=canvas.create_oval(30,30,50,50,fill=color) #starting default values for the ball
        """ Note: x and y coordinates for top left corner and x and y coordinates for the bottom right corner, and finally the fill colour for the oval
        """
        self.canvas.move(self.id,0,0) #this moves the oval to the specified location

    def draw(self): #we have created the draw method but it doesn't do anything yet.
        pass 


def main(): #this main part is the central part of the program that generally controls most of what it will do .....
    tk=Tk()
    tk.title("My 21st Century Pong Game")
    tk.resizable(0,0)
    tk.wm_attributes("-topmost",1)
    canvas=Canvas(tk,bg="white",width=500,height=400,bd=0,highlightthickness=0)
    canvas.pack()
    tk.update()

    ball1=Ball(canvas,'green') #here we are creating an object (green ball) of the class Ball
    while 1:
        tk.update()
        ball1.draw() #call the ball draw method here
        time.sleep(0.01)
   
main()

Systems Life Cycle (in a nutshell): Analyse - Design - Create - Test - Evaluate. Designing something or writing out some pseudocode before you actually write code is always a good idea! Get in to the habit of doing so! You can draw your flowchart here and screenshot it.

A sample flow chart (design) for this particular challenge could look like:

Each challenge section below provides an online drawing tool where you can dynamically create flowcharts. Screenshot them into your presentation for submission.

Testing Table

You may want to read a little about Testing first. A teacher may go through some examples with you. Feel free to fill in the test table here, and screenshot it in to your powerpoint. Testing is absolutely essential once you have created a program!

Test No.	Description	Test Data(input)	Expected Outcome	Actual Outcome	Further Action?
1	Describe your test here. Is it a valid, valid-extreme,invalid, invalid extreme, or borderline test?
