How to Draw a Square Using Turtle in Python

Use the turtle module in Python to draw a square by moving the turtle forward and turning it 90 degrees four times. The basic commands are forward() to move and right(90) to turn right by 90 degrees.

📐

Syntax

The basic syntax to draw a square with turtle involves these steps:

import turtle: Loads the turtle module.
t = turtle.Turtle(): Creates a turtle object to draw.
t.forward(distance): Moves the turtle forward by the specified distance.
t.right(angle): Turns the turtle right by the specified angle in degrees.
turtle.done(): Keeps the window open until closed by the user.

python

import turtle

t = turtle.Turtle()
t.forward(100)  # Move forward by 100 units
t.right(90)     # Turn right by 90 degrees
turtle.done()

💻

Example

This example draws a complete square by repeating the forward and right turn commands four times.

python

import turtle

t = turtle.Turtle()

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

turtle.done()

Output

A window opens showing a square drawn by the turtle cursor.

⚠️

Common Pitfalls

Common mistakes when drawing a square with turtle include:

Forgetting to call turtle.done(), which closes the window immediately.
Using incorrect turn angles (not 90 degrees) which results in shapes other than a square.
Not repeating the forward and turn commands exactly four times.

python

import turtle

t = turtle.Turtle()

# Wrong: turning 60 degrees instead of 90
for _ in range(4):
    t.forward(100)
    t.right(60)  # Incorrect angle

turtle.done()

Output

The turtle draws a shape with 60-degree turns, not a square.

📊

Quick Reference

Remember these key commands for drawing shapes with turtle:

Command	Description
`t.forward(distance)`	Move turtle forward by distance
`t.right(angle)`	Turn turtle right by angle degrees
`t.left(angle)`	Turn turtle left by angle degrees
`turtle.done()`	Keep window open until closed

✅

Key Takeaways

Use t.forward() and t.right(90) four times to draw a square.

Always call turtle.done() to keep the drawing window open.

Turning by exactly 90 degrees is essential for a perfect square.

Repeat the move and turn commands four times for four sides.

Import the turtle module and create a turtle object before drawing.
