Write a program that prints
We like Python's turtles!100 times.
turtle-8-5: Turtle objects have methods and attributes. For example, a turtle has a position and when you move the turtle forward, the position changes. Think about the other methods shown in the summary above. Which attibutes, if any, does each method relate to? Does the method change the attribute?
- Write a program that uses a for loop to print
One of the months of the year is January
One of the months of the year is February
One of the months of the year is Marchetc …
Assume you have a list of numbers
12, 10, 32, 3, 66, 17, 42, 99, 20
Write a loop that prints each of the numbers on a new line.
Write a loop that prints each number and its square on a new line.
forloops to make a turtle draw these regular polygons (regular means all sides the same lengths, all angles the same):
An equilateral triangle
A hexagon (six sides)
An octagon (eight sides)
# draw an equilateral triangle import turtle wn = turtle.Screen() norvig = turtle.Turtle() for i in range(3): norvig.forward(100) # the angle of each vertice of a regular polygon # is 360 divided by the number of sides norvig.left(360/3) wn.exitonclick()
# draw a square import turtle wn = turtle.Screen() kurzweil = turtle.Turtle() for i in range(4): kurzweil.forward(100) kurzweil.left(360/4) wn.exitonclick()
# draw a hexagon import turtle wn = turtle.Screen() dijkstra = turtle.Turtle() for i in range(6): dijkstra.forward(100) dijkstra.left(360/6) wn.exitonclick()
# draw an octogon import turtle wn = turtle.Screen() knuth = turtle.Turtle() for i in range(8): knuth.forward(75) knuth.left(360/8) wn.exitonclick()
Write a program that asks the user for the number of sides, the length of the side, the color, and the fill color of a regular polygon. The program should draw the polygon and then fill it in.
A drunk pirate makes a random turn and then takes 100 steps forward, makes another random turn, takes another 100 steps, turns another random amount, etc. A social science student records the angle of each turn before the next 100 steps are taken. Her experimental data is
160, -43, 270, -97, -43, 200, -940, 17, -86. (Positive angles are counter-clockwise.) Use a turtle to draw the path taken by our drunk friend. After the pirate is done walking, print the current heading.
On a piece of scratch paper, trace the following program and show the drawing. When you are done, press

Write a program to draw a shape like this:
Write a program to draw a face of a clock that looks something like this:
Create a turtle and assign it to a variable. When you print its type, what do you get?
A sprite is a simple spider shaped thing with n legs coming out from a center point. The angle between each leg is 360 / n degrees.
Write a program to draw a sprite where the number of legs is provided by the user.
