Drawing Two Pentagrams with Python

Drawing shapes, including pentagrams, with Python is a fun and educational way to explore the capabilities of this versatile programming language. In this article, we will discuss how to draw two pentagrams using Python, specifically leveraging the turtle graphics library. This library is great for beginners as it allows for easy visualization of programming concepts through graphics.

Step 1: Setting Up the Environment

Before we start coding, ensure that you have Python installed on your computer. The turtle module is part of Python’s standard library, so you don’t need to install anything extra.

Step 2: Basic Understanding of Turtle Graphics

The turtle module enables users to create graphics by controlling a turtle on a screen. You can move the turtle forward or backward, turn left or right, and even change the turtle’s speed and color.

Step 3: Drawing a Pentagram

A pentagram is a five-pointed star drawn with five straight lines. Here’s how you can draw one with Python:

pythonCopy Code
import turtle

def draw_pentagram(turtle, size):
    angle = 144
    turtle.forward(size)
    for _ in range(4):
        turtle.right(angle)
        turtle.forward(size)

# Set up the screen
screen = turtle.Screen()
screen.bgcolor("white")

# Create a turtle
star_turtle = turtle.Turtle()
star_turtle.speed(1)

# Draw the pentagram
draw_pentagram(star_turtle, 100)

# Hide the turtle after drawing
star_turtle.hideturtle()

# Keep the window open
turtle.done()

Step 4: Drawing Two Pentagrams

Drawing two pentagrams is similar to drawing one, but you need to manage the position of each star carefully. Here’s how you can do it:

pythonCopy Code
import turtle

def draw_pentagram(turtle, size):
    angle = 144
    turtle.forward(size)
    for _ in range(4):
        turtle.right(angle)
        turtle.forward(size)

screen = turtle.Screen()
screen.bgcolor("white")

# Create two turtles for two pentagrams
star1_turtle = turtle.Turtle()
star1_turtle.speed(1)
star1_turtle.color("blue")

star2_turtle = turtle.Turtle()
star2_turtle.speed(1)
star2_turtle.color("red")
star2_turtle.penup()
star2_turtle.goto(150, -50)  # Move the second turtle to a new position
star2_turtle.pendown()

# Draw the pentagrams
draw_pentagram(star1_turtle, 100)
draw_pentagram(star2_turtle, 70)

# Hide the turtles after drawing
star1_turtle.hideturtle()
star2_turtle.hideturtle()

turtle.done()

In this code, we created two turtles, each with a different color, and drew two pentagrams of different sizes at different positions on the screen.

Conclusion

Drawing shapes like pentagrams with Python’s turtle module is a great way to learn programming fundamentals while creating visually appealing graphics. By adjusting the parameters and adding more shapes, you can create complex and interesting designs.
