Let’s draw! Open Python IDLE editor… …go to File -> New File… …and type this code in: ü ANALYSE the code to draw different lengths and turn by different amounts - What do the numbers in brackets mean? ü IMPROVE the program to draw a complete square and a triangle - Can you change the colour of the lines? How? ü CREATE a program to draw a house with windows and doors - How can you move the turtle without leaving a line?

Let’s draw! Here’s the code for the triangle: ü ORGANISE the code to draw triangles of different sizes ü IMPROVE the program to use different colour pens - Can you draw a triangle with a different colour for each side? ü CREATE a program to draw a circle - can you fill the circle with a colour?
