Step 3 – Square turtle
Now you can turn a turtle, you can draw a square.
Problem – draw a square
- Use this code as a starting point to draw a square using the turtle
How many sides does a square have?
- Run your code and check that the turtle draws a square
Notice where the turtle ends up and what direction it's facing in. That might be important later on.
Notice that I added a line of code above my program to say what it does. The line starts with a hash symbol #.
This is a comment. Comments are used to tell people what the code does. The computer sees the hash symbol and ignores the rest of the line.
Comments are really useful to include in your code.
If right(90) is used to turn the turtle 90° to the right, how do you think you can turn the turtle to the left? Hint: it's not too tricky...
