Drawing a Square with Python: A Beginner’s Guide

Drawing a square with Python is a fundamental exercise that can help beginners grasp the basics of programming, especially when working with graphics or simple output formatting. Python, being a versatile language, offers multiple ways to accomplish this task. In this guide, we will explore a simple method using the turtle module, which is part of Python’s standard library and is especially suited for introductory programming tasks.

Step 1: Importing the Turtle Module

First, you need to import the turtle module. This module provides a simple way to create graphics and is often used to introduce programming to kids.

pythonCopy Code
import turtle

Step 2: Setting Up the Turtle

Before drawing, it’s a good practice to set up your ‘turtle’—the cursor that draws on the screen. You can control its speed, for instance, using the speed() method.

pythonCopy Code
turtle.speed(1)  # Set the speed to slow for better visualization

Step 3: Drawing the Square

Drawing a square involves moving the turtle forward a certain distance and then turning 90 degrees four times.

pythonCopy Code
for _ in range(4):
    turtle.forward(100)  # Move forward by 100 units
    turtle.right(90)     # Turn right by 90 degrees

Step 4: Keeping the Window Open

After drawing the square, the turtle graphics window might close immediately. To prevent this, you can add turtle.done() at the end of your script.

pythonCopy Code
turtle.done()

Full Code

Here’s the complete code to draw a square using Python’s turtle module:

pythonCopy Code
import turtle

turtle.speed(1)

for _ in range(4):
    turtle.forward(100)
    turtle.right(90)

turtle.done()

Running this script will open a new window showing the turtle drawing a square. You can modify the forward() method’s parameter to change the size of the square or adjust the speed() method’s parameter to make the drawing faster or slower.

Learning to draw simple shapes like a square is a great start to exploring more complex graphics and programming concepts in Python. As you progress, you can experiment with different shapes, colors, and even create interactive graphics applications.
