Drawing Four Circles Using Python: A Comprehensive Guide

Drawing circles in Python can be accomplished through various libraries, with the most popular one being matplotlib. This guide will walk you through the process of drawing four circles using Python, specifically leveraging the capabilities of matplotlib.

Step 1: Install Matplotlib

Before we start coding, ensure that you have matplotlib installed in your Python environment. If you haven’t installed it yet, you can do so by running the following command in your terminal:

bashCopy Code
pip install matplotlib

Step 2: Import Necessary Libraries

In your Python script or Jupyter Notebook, import the necessary libraries:

pythonCopy Code
import matplotlib.pyplot as plt

Step 3: Draw Four Circles

We will use plt.Circle to create circles. This function requires the center coordinates and the radius of the circle. Let’s draw four circles with different sizes and positions.

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

# Circle 1
circle1 = plt.Circle((0.2, 0.5), 0.1, color='blue', fill=True)
ax.add_artist(circle1)

# Circle 2
circle2 = plt.Circle((0.5, 0.5), 0.2, color='green', fill=True)
ax.add_artist(circle2)

# Circle 3
circle3 = plt.Circle((0.7, 0.2), 0.15, color='red', fill=True)
ax.add_artist(circle3)

# Circle 4
circle4 = plt.Circle((0.3, 0.1), 0.05, color='purple', fill=True)
ax.add_artist(circle4)

ax.set_xlim(0, 1)  # Set the x limits
ax.set_ylim(0, 1)  # Set the y limits

plt.show()  # Display the figure

This code snippet creates a figure and an axes, then adds four circles with specified positions, sizes, and colors. Finally, it sets the limits of the x and y axes and displays the figure.

Conclusion

Drawing circles in Python using matplotlib is a straightforward process. By leveraging the plt.Circle function, you can easily create circles with specific attributes such as position, size, and color. This guide has walked you through the steps to draw four circles, demonstrating the flexibility and simplicity of using matplotlib for basic geometric drawings.
