Question

I need to write these three functions in Python using turtle module.

def line(t, coord1, coord2)

• t is a turtle object passed in
• coord1 and coord2 are 2-element lists that represent x, y coordinates
• draws a line from coord1 to cord2

def poly(t, *coords)

• t is a turtle object passed in
• *coords is any number of x, y coordinates each as a 2-element list
• draws a polygon based on coords (will close off polygon by drawing a line from last coord to first)

def rectangle(t, coord, width, height, color)

• t is a turtle object passed in
• coord is upper left corner of rectangle
• assume width and height are ints
• color is the color to fill with
• (use t.color('red'), t.begin_fill(), and t.end_fill())

Answer 1

Function 1: line

Code:-

import turtle

def line(t, coord1, coord2):
        t.penup()
        t.goto((coord1[0], coord1[1]))
        t.pendown()
        t.goto((coord2[0], coord2[1]))

line(turtle, [50, 100], [100, 50])
turtle.hideturtle()
turtle.exitonclick()

Screenshot:-

Output:-

Function 2: Polygon

Code:-

import turtle

def poly(t, *coords):
        t.penup()
        t.goto(coords[0])
        t.pendown()
        i = 0
        while i < len(coords)-1:
                t.goto(coords[i+1])
                i += 1

        t.goto(coords[0])

poly(turtle, [50, 100], [100, 50], [0, 50], [0, 200], [200, 100])
turtle.hideturtle()
turtle.exitonclick()

Output:-

Function 3: Rectangle

Code:-

import turtle

def rectangle(t, coord, width, height, color):
        t.fillcolor(color)
        t.pencolor(color)
        t.begin_fill()

        t.penup()
        t.goto(coord)
        t.pendown()
        t.goto([coord[0]+width, coord[1]]) #Goes to the co ordinate width pixels to the right
        t.goto([coord[0]+width, coord[1]+height]) #Goes to the point width pixels to the right and height pixels down
        t.goto([coord[0], coord[1]+height]) #Goes to the point height pixels down
        t.goto(coord)#Back to start

        t.end_fill()

rectangle(turtle, [100, 50], 100, 50, "red")
turtle.hideturtle()
turtle.exitonclick()
