Drawing a Pentagon with 100 Pixels in Python

Drawing geometric shapes using Python is an engaging way to learn programming fundamentals while exploring computer graphics. This article will guide you through the process of drawing a pentagon with each side being 100 pixels long using Python. We’ll utilize the Turtle graphics module, which is part of Python’s standard library and is perfect for creating simple graphics and understanding basic programming concepts.

Step 1: Import the Turtle Module

First, you need to import the turtle module. This module provides a simple way to create graphics by controlling a turtle that moves around the screen.

pythonCopy Code
import turtle

Step 2: Set Up the Turtle

Before drawing, let’s set up our turtle by defining the speed and initial position.

pythonCopy Code
# Create a turtle instance
pen = turtle.Turtle()

# Set the speed of the turtle
pen.speed(1)

Step 3: Drawing the Pentagon

To draw a pentagon, we need to draw five lines, each of length 100 pixels, connected end to end. The interior angle of a pentagon is 108 degrees.

pythonCopy Code
# Function to draw a pentagon
def draw_pentagon(side_length):
    angle = 108
    for _ in range(5):
        pen.forward(side_length)
        pen.right(angle)

# Draw a pentagon with side length of 100 pixels
draw_pentagon(100)

Step 4: Keep the Window Open

After drawing, the graphics window might close immediately. To prevent this, we use turtle.done() to keep the window open until it’s manually closed.

pythonCopy Code
turtle.done()

Complete Code

Here’s the complete code to draw a pentagon with each side being 100 pixels long.

pythonCopy Code
import turtle

# Create a turtle instance
pen = turtle.Turtle()

# Set the speed of the turtle
pen.speed(1)

# Function to draw a pentagon
def draw_pentagon(side_length):
    angle = 108
    for _ in range(5):
        pen.forward(side_length)
        pen.right(angle)

# Draw a pentagon with side length of 100 pixels
draw_pentagon(100)

# Keep the window open
turtle.done()

Running this code will open a graphics window showing a pentagon with each side being 100 pixels long.
