Chapter 1

Introduction to Python

1.1Introduction

Before we begin discussion on image acquisition and processing using Python, we will provide an overview of the various aspects of Python. This chapter focuses on some of the basic materials covered by many other books [Bea09], [Het10], [Lut06], [Vai09] and also from the book, “Essential Python” ([PC18]), a book from the authors of this book. If you are already familiar with Python and are currently using it, then you can skip this chapter.

We begin with an introduction to Python. We will then discuss the installation of Python with all the modules using the Anaconda distribution. Once the installation has been completed, we can begin exploring the various features of Python. We will quickly ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
