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.

Chapter 11. Debugging and Troubleshooting

 

"If debugging is the process of removing software bugs, then programming must be the process of putting them in."

 
 --Edsger W. Dijkstra

In the life of a professional coder, debugging and troubleshooting take up a significant amount of time. Even if you work on the most beautiful codebase ever written by man, there will still be bugs in it, that is guaranteed.

We spend an awful lot of time reading other people's code and, in my opinion, a good software developer is someone who keeps their attention high, even when they're reading code that is not reported to be wrong or buggy.

Being able to debug code efficiently and quickly is a skill that any coder needs to keep improving. Some think that because they have read the manual, they're fine, but the reality is, the number of variables in the game is so big that there is no manual. There are guidelines that one can follow, but there is no magic book that will teach you everything you need to know in order...
