How to Open PNG and JPG Files in Python: A Step-by-Step Guide

If you're venturing into the world of Python and image processing, you might have wondered how to easily open and display PNG or JPG files. It can be frustrating when you come across errors while trying to work with these images, like the AttributeError caused by circular imports. In this guide, we’ll discuss a common problem faced when opening images in Python and provide a clear solution you can implement right away!

The Problem: Encountering Errors when Opening Images

Many beginners often try to use the PIL (Python Imaging Library) to open image files, but end up receiving errors such as:

This error can be confusing, especially if you're just getting started. It usually occurs when the module is not correctly imported. Fortunately, there is a way around this issue!

The Solution: Using matplotlib to Open Images

Instead of relying on PIL, you can use the matplotlib library which provides functions for image representation. Here’s a simple step-by-step solution to open and display PNG or JPG files in Python.

Step 1: Import Required Libraries

First, make sure you have matplotlib installed. You can install it using pip if you haven't done so already:
