Here's a short Python program to create a pattern with coloured circles:
from turtle import * pensize(5) for i in range(4): for c in ["red","green","blue"]: pencolor(c) circle(100) right(30) exitonclick()
Create a new Geany file, enter the Python code, save it as
turtle-patterns.pyand execute the program. After you've seen it run modify the code to experiment with different pen sizes, colour names and circle diameters.
