Drawing Four Circles with Python: A Simple Guide

Python, with its powerful libraries such as Turtle and Matplotlib, offers an intuitive way to create graphical representations, including drawing circles. This article will guide you through the process of drawing four circles using Python. Whether you’re a beginner or someone looking to refresh your skills, this simple guide will help you get started.

Using Turtle Graphics

Turtle is a popular choice for beginners due to its simplicity. Here’s how you can draw four circles using Turtle:

pythonCopy Code
import turtle

# Set up the screen
screen = turtle.Screen()
screen.title("Four Circles with Turtle")

# Create a turtle
pen = turtle.Turtle()
pen.speed(1)  # Set the drawing speed

# Function to draw a circle
def draw_circle(color, x, y):
    pen.up()
    pen.goto(x, y)
    pen.down()
    pen.color(color)
    pen.begin_fill()
    pen.circle(50)  # Draw a circle with radius 50
    pen.end_fill()

# Draw four circles
draw_circle("red", -100, 0)
draw_circle("blue", 0, 100)
draw_circle("green", 100, 0)
draw_circle("yellow", 0, -100)

# Hide the turtle cursor
pen.hideturtle()

# Keep the window open
turtle.done()

This code snippet will create a window displaying four circles of different colors, each positioned at a different location on the screen.

Using Matplotlib

Matplotlib is another powerful library for creating static, animated, and interactive visualizations in Python. Here’s how you can use it to draw four circles:

pythonCopy Code
import matplotlib.pyplot as plt

# Create a figure and an axes
fig, ax = plt.subplots()

# Draw four circles
circles = [plt.Circle((x, y), 50, color=color, fill=True) for x, y, color in [(-100, 0, 'red'), (0, 100, 'blue'), (100, 0, 'green'), (0, -100, 'yellow')]]

# Add the circles to the axes
for c in circles:
    ax.add_artist(c)

# Set the limits of the axes
ax.set_xlim(-150, 150)
ax.set_ylim(-150, 150)
ax.set_aspect('equal', adjustable='box')

# Show the plot
plt.show()

This code will generate a plot showing four circles, similar to the Turtle example, but with more flexibility in terms of customization and integration with other Matplotlib features.

Drawing circles with Python is a fundamental skill that can be extended to create more complex visualizations and simulations. Both Turtle and Matplotlib are versatile tools that can help you bring your ideas to life, whether you’re working on a personal project or contributing to a larger application.
