Learning Python

By: Romano

Overview of this book

Learning Python has a dynamic and varied nature. It reads easily and lays a good foundation for those who are interested in digging deeper. It has a practical and example-oriented approach through which both the introductory and the advanced topics are explained. Starting with the fundamentals of programming and Python, it ends by exploring very different topics, like GUIs, web apps and data science. The book takes you all the way to creating a fully fledged application. The book begins by exploring the essentials of programming, data structures and teaches you how to manipulate them. It then moves on to controlling the flow of a program and writing reusable and error proof code. You will then explore different programming paradigms that will allow you to find the best approach to any situation, and also learn how to perform performance optimization as well as effective debugging. Throughout, the book steers you through the various types of applications, and it concludes with a complete mini website built upon all the concepts that you learned.

Testing your application


There are many different kinds of tests, so many in fact that companies often have a dedicated department, called quality assurance (QA), made up of individuals that spend their day testing the software the company developers produce.

To start making an initial classification, we can divide tests into two broad categories: white-box and black-box tests.

White-box tests are those which exercise the internals of the code, they inspect it down to a very fine level of granularity. On the other hand, black-box tests are those which consider the software under testing as if being within a box, the internals of which are ignored. Even the technology, or the language used inside the box is not important for black-box tests. What they do is to plug input to one end of the box and verify the output at the other end, and that's it.

Note

There is also an in-between category, called gray-box testing, that involves testing a system in the same way we do with the black-box approach...
