Drawing Four Circles in Python: A Step-by-Step Guide

Drawing circles in Python can be an engaging and educational experience, especially when using libraries like Turtle or Matplotlib. In this guide, we’ll explore how to draw four circles using both libraries, providing you with a foundational understanding of creating basic shapes in Python.
‌Using Turtle Graphics‌:

Turtle is a popular library in Python that provides a simple way to create graphics and understand basic programming concepts. Here’s how you can use Turtle to draw four circles:

1.‌Import the Turtle Library‌:

pythonCopy Code
import turtle

2.‌Set Up the Screen‌:
Before drawing, you might want to set up the screen for better visualization.

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

3.‌Create a Turtle Instance‌:
This turtle instance will be used to draw the circles.

pythonCopy Code
pen = turtle.Turtle()
pen.speed(1)  # Adjust the speed of the turtle

4.‌Draw Four Circles‌:
Use the circle method to draw circles. You can vary the size and position by adjusting the radius and using the penup() and pendown() methods for movement without drawing.

pythonCopy Code
for _ in range(4):
    pen.circle(50)  # Draw a circle with radius 50
    pen.penup()
    pen.forward(120)  # Move the pen forward by 120 units
    pen.pendown()

5.‌Hide the Turtle and Keep the Window Open‌:

pythonCopy Code
pen.hideturtle()
turtle.done()

‌Using Matplotlib‌:

Matplotlib is a more advanced library used for plotting and data visualization in Python. Here’s how you can draw four circles using Matplotlib:

1.‌Import the Matplotlib Library‌:

pythonCopy Code
import matplotlib.pyplot as plt

2.‌Create a Figure and an Axes Object‌:

pythonCopy Code
fig, ax = plt.subplots()

3.‌Draw Four Circles‌:
Use the Circle function from the matplotlib.patches module to create circles. You can specify the center and radius of each circle.

pythonCopy Code
from matplotlib.patches import Circle

circles = [Circle((x, y), radius=0.4, fill=False) for x, y in [(0.5, 0.5), (1.5, 0.5), (0.5, 1.5), (1.5, 1.5)]]

for c in circles:
    ax.add_patch(c)

4.‌Set the Limits of the Axes‌:
This ensures that all circles are visible.

pythonCopy Code
ax.set_xlim(0, 2)
ax.set_ylim(0, 2)

5.‌Show the Plot‌:

pythonCopy Code
plt.show()

Both methods offer a straightforward way to draw circles in Python, with Turtle being more suited for beginners and educational purposes, while Matplotlib provides a powerful tool for data visualization and complex graphics.
