#Thonny raspberry pi pygame code#
Type the following, making sure to pay close attention to indentation – because at one point you’re going to be nesting code three indentation levels deep! for i in range(3): for i in range(3): pat.forward(30) pat.backward(30) pat.right(45) pat.left(90) pat.backward(30) pat.left(45) pat.right(90) pat.forward(90) Finally, create a new loop at the bottom of your program – but above the commented-out colour line – to run, or call, your new function: for i in range(8): branch() pat.left(45) Chapter 5 Programming with Python 101 When you press the ENTER key, Thonny will automatically add indentation for the function’s instructions.
You can use comments to add explanations to your code, which will make it a lot easier to understand when you come back to it a few months later or send it on to someone else! Create your function, which will be called ‘branch’, by typing the following instruction onto line 10, below pat.pendown(): def branch(): This defines your function, branch. This is known as commenting out an instruction, and means that Python will ignore it. Leave the pat.color(random.choice(colours)) instruction, but add a hash symbol (#) at the start of the line.
THE OFFICIAL RASPBERRY PI BEGINNER’S GUIDE Start by deleting the code for drawing your parallelogram-based snowflakes: that’s everything between and including the pat.color(\"cyan\") instruction on line 10 through to pat.right(36) on line 17.
