2.10.5 Sidewalk CodeHS Answers

The most common answer is:

speed(0)
def draw_square():
or i in range (4):
forward(50)
right(90)
def square_dance():
for i in range (8):
draw_square()
forward(50)
penup()
setposition (-200,200)
pendown()
def square_dancing():
for i in range(4):
square_dance()
right(90)
square_dancing()

This code snippet aims to create a pattern that could resemble a sidewalk or a “square dance” by drawing squares and repeating them in a certain layout.

However, there’s a minor syntax issue in your draw_square function definition, and the overall structure could be optimized for clarity. Let’s correct and streamline your code for better execution:

import turtle

turtle.speed(0)  # Set the drawing speed to the fastest

# Function to draw a single square
def draw_square():
    for _ in range(4):
        turtle.forward(50)  # Length of each side of the square
        turtle.right(90)  # Turn right to make the next side of the square

# Function to draw a row of squares
def square_dance():
    for _ in range(8):  # Draw 8 squares in a row
        draw_square()
        turtle.forward(50)  # Move to the start position for the next square

# Function to position the turtle before starting the square dance
def setup_position():
    turtle.penup()
    turtle.setposition(-200, 200)  # Start position
    turtle.pendown()

# Main function to create the sidewalk pattern
def square_dancing():
    setup_position()
    for _ in range(4):  # Repeat the square dance in 4 directions
        square_dance()
        turtle.right(90)  # Turn to start the next row in a new direction

square_dancing()

turtle.done()  # Keep the window open until manually closed

This revised version introduces a structured approach:

draw_square: Defines how to draw a single square.
square_dance: Uses draw_square to create a row of 8 squares, moving forward between each square to position for the next one.
setup_position: Moves the turtle to the starting position for the pattern.
square_dancing: Calls square_dance four times, rotating 90 degrees after each call to create a pattern that extends in four directions from the starting point.

The import turtle at the beginning ensures you have access to turtle graphics functions. The setup_position function is called before starting the square dance to position the turtle correctly. This setup creates a pattern that could visually represent a sidewalk or a decorative pattern, with each “square dance” creating a line of squares that rotate around a central point.
