The most common answer for the 4.9.6 Random Color Square CodeHS is:
import random
set_size(480, 400)
This graphics program should draw a square.
The fill color should be randomly choosen from
the COLORS list
center_x = get_width() / 2
center_y = get_height() / 2
SIDE_LENGTH = 100
COLORS = [Color.red, Color.orange, Color.yellow, Color.green, Color.blue,
Color.purple, Color.black, Color.gray]
square = Rectangle(SIDE_LENGTH, SIDE_LENGTH)
square.set_position(center_x, center_y)
square.set_color(random.randint(COLORS))
add(square)
This code for drawing a square with a random color from the COLORS
list is almost correct, but there’s a minor issue in the random.randint(COLORS)
part. random.randint()
is used for generating random integers and is not suitable for selecting a random element from a list.
Instead, we should use random.choice()
to select a random color from the COLORS
list. Additionally, the square’s position needs to be adjusted to ensure it’s centered.
Here’s the corrected version of the code:
import random
set_size(480, 400)
center_x = get_width() / 2 - SIDE_LENGTH / 2 # Adjust to center the square
center_y = get_height() / 2 - SIDE_LENGTH / 2 # Adjust to center the square
SIDE_LENGTH = 100
# List of colors
COLORS = [Color.red, Color.orange, Color.yellow, Color.green, Color.blue,
Color.purple, Color.black, Color.gray]
# Create a square
square = Rectangle(SIDE_LENGTH, SIDE_LENGTH)
# Set the position and random color of the square
square.set_position(center_x, center_y)
square.set_color(random.choice(COLORS)) # Choose a random color
# Add the square to the canvas
add(square)
In this corrected code:
random.choice(COLORS)
is used to select a random color from theCOLORS
list.- The
center_x
andcenter_y
calculations are adjusted to account for the square’s dimensions, ensuring the square is truly centered on the canvas.
Run this code in a suitable Python graphics environment, and it should draw a square at the center of the canvas with a random color from the specified list.
