Last time: functions and for loops abstraction – remove the details of a concept generalization – you look at several specific concepts and develop a theory that works for all of them – you look at several specific problems (and solutions to those problems), you figure out the pattern (similarities & differences), and you develop a single solution that works for all of those specific problems drawPolygon - what are the similarities in how to draw all polygons - what are the differences - How can I write one function that takes advantage of the similarities but still accounts for the differences def drawSquare(turtle): turtle.forward(100) turtle.left(90) turtle.forward(100) turtle.left(90) turtle.forward(100) turtle.left(90) turtle.forward(100) turtle.left(90) def drawHexagon(turtle): turtle.forward(100) turtle.left(60) turtle.forward(100) turtle.left(60) turtle.forward(100) turtle.left(60) turtle.forward(100) turtle.left(60) turtle.forward(100) turtle.left(60) turtle.forward(100) turtle.left(60)
