Tracy wants a beaded bracelet for her birthday. Write a program that will draw one for her!

Question

The bracelet should follow these specifications:

There must be 36 beads
Each bead should have a radius of 10 pixels
The bracelet must have a diameter of 200
Tracy should draw the bracelet counterclockwise
Hints:

You will need to use a function and a loop in your code!
You will need to turn Tracy 10 degrees after drawing each bead
You should return to the middle of the bracelet circle between drawing each bead

Answer 1

To create a program that draws a beaded bracelet according to the specifications provided, we can use the Python turtle graphics library. Below is an example of how you could implement this:

import turtle

def draw_beaded_bracelet():
    # Set up the turtle environment
    turtle.speed(0)  # Set the turtle speed to the maximum
    turtle.penup()   # Don't draw when moving to the starting position
    turtle.goto(0, -100)  # Move turtle to the starting position (middle of the bracelet circle)
    turtle.pendown()  # Start drawing beads
    turtle.circle(100)  # Draw the outline of the bracelet (optional)
    
    # Draw 36 beads
    for i in range(36):
        # Draw the bead
        turtle.penup()
        turtle.goto(0, 0)  # Return to the center
        turtle.setheading(90 + i * 10)  # Set direction (90 degrees is straight up)
        turtle.forward(100)  # Move to the edge of the bracelet circle
        turtle.pendown()
        turtle.circle(10)    # Draw bead with radius 10 pixels
        turtle.penup()

    turtle.hideturtle()  # Hide the turtle cursor
    turtle.done()  # Finish the drawing

# Call the function to draw the bracelet
draw_beaded_bracelet()

Explanation:

• We import the turtle module which allows us to create graphics.
• The draw_beaded_bracelet function is defined to encapsulate the drawing logic.
• Turtle's speed is set to 0 to draw as quickly as possible.
• The turtle starts at the center of the bracelet and moves down to the edge to start drawing.
• A loop runs 36 times to draw each bead, with each iteration adjusting the angle by 10 degrees counterclockwise (based on its loop index).
• After positioning at the angle, the turtle moves forward to the edge of the bracelet, draws a circle with a radius of 10 pixels (the bead), and returns to the center before the next iteration.
• Finally, turtle.done() is called to finish drawing and keep the window open until the user closes it.

To execute this code, you simply need to run it in a Python environment that supports turtle, such as IDLE or an appropriate IDE that allows GUI operations.
