Question

Part One: Write a program to draw a repetitive pattern or outline of a shape using for loops and Turtle Graphics. Use the following guidelines to write your program.

1. Decide on a repetitive pattern or the outline of a shape, such as a house, to draw.
2. Give your artwork a name. Print the name to the output.
3. Using for loops and the Turtle Module, draw the outline of a shape or a repetitive pattern.
4. At least one for loop that repeats three or more times must be used.
5. Use at least one color apart from black.
6. Write the pseudocode for this program. Be sure to include any needed input, calculations, and output.

Insert your pseudocode here:

Part Two: Code the program. Use the following guidelines to code your program.

1. To code the program, use the Python IDLE.
2. Using comments, type a heading that includes your name, today’s date, and a short description of the program.
3. Follow the Python style conventions regarding indentation and the use of white space to improve readability.
4. Use meaningful variable names.

Answer 1

import turtle

# Creates a Turtle
draw = turtle.Turtle()

# Defines a function to draw a square
def squarePattern():
# Sets the background color
turtle.bgcolor("light green")
# Sets the pen color to red
draw.color("red")

# Loops 4 times
for times in range(4):
# Moves the pen forward
draw.forward(50)
# Turn the pen right side
draw.right(90)
turtle.done()
  
def starPattern():
# Sets the background color
turtle.bgcolor("blue")
# Sets the pen color white
draw.color("white")

# Loops 5 times
for times in range(5):
# Moves the pen forward
draw.forward(50)
# Moves the pen right
draw.right(144)   
turtle.done()

def polygonPattern():
# Sets the background color
turtle.bgcolor("yellow")
# Accepts number of sides of polygon
sides = int(input("Enter number of sides: "))
# Calculates the angle
angle = 360.0 / sides  

# Loops number of side times
for times in range(sides):
# Moves the pen forward
draw.forward(80)
# Moves the pen right
draw.right(angle)
turtle.done()

# Displays menu  
print("************* MENU ************* ")
print("S - Star")
print("P - Polygon")
print("Q - Square")

# Accepts user choice   
ch = input("Enter your choice: ")

# Checks if user choice is upper case 'S' or lower case 's'
if ch == 'S' or ch == 's':
# Calls the function to draw
starPattern()

# Checks if user choice is upper case 'P' or lower case 'P'
elif ch == 'P' or ch == 'p':
# Calls the function to draw
polygonPattern()

# Checks if user choice is upper case 'Q' or lower case 'q'
elif ch == 'Q' or ch == 'q':
# Calls the function to draw
squarePattern()
else:
print("Invalid move. Try again!")
