Problem Set 8
Submit the following programs via Blackboard:
-
Due Date: 10 November
Write a program that uses turtle graphics to rotate your turtle. In your program, create a turtle named for you (for example, if your name is Tom, the name of your turtle variable should be tom). Ask the user to enter a number, n. If that number is even, your turtle should turn n degrees to the right. If that number is odd your turtle should turn n degrees to the left. After rotating, you should have your turtle walk forward 10 steps. For example, if n is even, you would have:tom.right(n) tom.forward(10)
If n is odd, you would have:tom.left(n) tom.forward(10)
Be sure to include code to close the window following a final mouse click. Points will be deducted if the grader's computer crashes. To do this with turtle graphics, use:scr.exitonclick()

Translate the following pseudocode into a python function that uses turtle graphics:
hexagon(turtle, x): while x > 10: for i = 0 to 6: move turtle forward x steps turn turtle 60 degrees to right x = x -10
Include in your submitted program a main function that creates a turtle and calls the the hexagon function with your turtle and 50 as the input parameters.

Use turtle graphics to simulate a random walk of 1000 steps. In your program, create a turtle named for you (for example, if your name is Tom, the name of your turtle variable should be tom). At every step, you should choose an angle between 0 and 360 degrees at random and have your turtle turn right by that angle and take 10 steps. For example, to make Tom's turtle turn a random angle and walk 10 steps, you could write:
angle = randrange(0,360) tom.right(angle) tom.forward(10)

Write a function that uses turtle graphics to draw a petal. Your function should take a turtle as its input parameter and draw a single petal. For example,
Draw a flower by repeatedly calling your function. Your flower should have at least 10 petals. For example,
(Note: you can change the color that your turtle, using the function, color(). For example, if you turtle is called flower to change it's color to purple, write flower.color("purple").)

Implement the following pseudo-code in a Python program.function leaf(turtle) Move turtle forward 50 steps Rotate turtle left 100 degrees Move turtle forward 30 steps Rotate turtle left 50 degrees Move turtle forward 30 steps Rotate turtle left 100 degrees Move turtle forward 50 steps Rotate turtle right 160 degrees function stem(turtle) Rotate turtle right 95 degrees Move turtle forward 70 steps Rotate turtle left 5 degrees Move turtle forward 70 steps function main() create a screen create a turtle loop four times leaf(turtle) stem(turtle) wait for click and close
