Copy, paste, amendThis is a starter activity and should take 5 minutes

[ slide 1 ]

1. Log in to your computer

2. Open myEtchASketch.py in IDLE

3. Check you have the code below:

4. Copy and paste the whole function and try to amend it to create a p1_move_S(self)function.

Lesson Aims

[ slide 2 ]

In this lesson you are going to:

1. practise writing functions

2. practise using tkinter’s lines widget

3. review how to add keyboard control to your game

4. finish the MyEtchASketch game

5. Open and customise a free two player Etch A Sketch® game

Finishing Off

[ slide 3 ]

1. Check your code for p1_move_N(self) is correct by looking at Code Box 5.4 on page 68 in Python Basics

2. Copy all the missing code from Code Box 5.4 into your Etch A Sketch® app

3. Test it out and make sure it works.

Top Tip:

There are four very similar functions supplied. It is quickest to copy the first function three more times and then amend it.

Whenever a coder keeps copying and pasting it hints that there is probably a better way of doing things.

What now?
