Creating a Starry Sky with Python: A Beginner’s Guide

Have you ever gazed at the night sky, marveling at the countless stars that seem to stretch infinitely? Recreating this celestial wonder on your computer screen using Python can be a fascinating project, not only for its visual appeal but also for the opportunity to practice programming skills. In this guide, we’ll explore how to generate a simple starry sky using Python, step by step.
‌Step 1: Setting Up Your Environment‌

Before diving into coding, ensure you have Python installed on your computer. Python 3.x is recommended for this project. Additionally, you’ll need a basic text editor or an Integrated Development Environment (IDE) like PyCharm, VSCode, or Jupyter Notebook to write your code.
‌Step 2: Understanding the Basics‌

To create a starry sky, we’ll use the turtle module, which is part of Python’s standard library. It’s a great tool for beginners to learn programming fundamentals while creating graphics and simple games.
‌Step 3: Coding Your Starry Sky‌

1.‌Import the Turtle Module‌: Start by importing the turtle module.

pythonCopy Code
import turtle

2.‌Set Up the Screen‌: Use the Screen() method to set the background color to black, mimicking the night sky.

pythonCopy Code
screen = turtle.Screen()
screen.bgcolor("black")

3.‌Create the Stars‌: Define a function to draw stars. You can use the forward() and right() methods to create the shape of a star. Remember, a star can be simplified into a series of lines connected at specific angles.

pythonCopy Code
def draw_star(turtle, size):
    angle = 144
    for _ in range(5):
        turtle.forward(size)
        turtle.right(angle)
        turtle.forward(size)
        turtle.right(72 - angle)

4.‌Drawing Multiple Stars‌: Use a loop to draw multiple stars of different sizes at random positions.

pythonCopy Code
star = turtle.Turtle()
star.speed(0)
star.color("white")

for _ in range(100):  # Adjust the number of stars
    x = random.randint(-300, 300)
    y = random.randint(-300, 300)
    size = random.randint(10, 20)
    star.penup()
    star.goto(x, y)
    star.pendown()
    draw_star(star, size)

5.‌Hide the Turtle Cursor‌: To make the final image look cleaner, hide the turtle cursor.

pythonCopy Code
star.hideturtle()

6.‌Keep the Window Open‌: Use turtle.done() to prevent the window from closing immediately after drawing the stars.

pythonCopy Code
turtle.done()

‌Step 4: Running Your Code‌

Save your code in a file with a .py extension, for example, starry_sky.py. Open a terminal or command prompt, navigate to the directory where your file is saved, and run the script by typing python starry_sky.py.
‌Conclusion‌

Creating a starry sky with Python is a delightful way to explore basic programming concepts while enjoying the beauty of the cosmos on your screen. As you gain more experience, you can experiment with adding more features, such as shooting stars, constellations, or even a moon. Happy coding!
