Based in part on over 3,000 newsgroup articles written by Python veteran Fredrik Lundh since 1995, this book provides brief descriptions and sample scripts for all standard modules in the Python 2. Lott Python network programming pdf-10: 1786469251 Year: 2016 Pages: 824 Language: English File size: 9. Book Description: Python is the preferred choice of developers, engineers, data scientists, and hobbyists everywhere.
It is a great scripting language that can power your applications and provide great speed, safety, and scalability. By exposing Python as a series of simple recipes, you can gain insight into specific language features in a particular context. This book comes with over 100 recipes on the latest version of Python. The recipes will benefit everyone ranging from beginner to an expert. The book is broken down into 13 chapters that build from simple language concepts to more complex applications of the language. The recipes will touch upon all the necessary Python concepts related to data structures, OOP, functional programming, as well as statistical programming. You will get acquainted with the nuances of Python syntax and how to effectively use the advantages that it offers.
You will end the book equipped with the knowledge of testing, web services, and configuration and application integration tips and tricks. The recipes take a problem-solution approach to resolve issues commonly faced by Python programmers across the globe. You will be armed with the knowledge of creating applications with flexible logging, powerful configuration, and command-line options, automated unit tests, and good documentation.

Professional Python goes beyond the basics to teach beginner- and intermediate-level Python programmers the little-known tools and constructs that build concise, maintainable code. Design better architecture and write easy-to-understand code using highly adoptable techniques that result in more robust and efficient applications. Python offers many tools and techniques for writing better code, but often confusing documentation leaves many programmers in the dark about how to use them. This book shines a light on these incredibly useful methods, giving you clear guidance toward building stronger applications. More than just theory or a recipe-style walk-through, this guide helps you learn — and understand — these little-known tools and techniques.
You’ll streamline your workflow while improving the quality of your output, producing more robust applications with cleaner code and stronger architecture. If you’re ready to take your Python skills to the next level, Professional Python is the invaluable guide that will get you there.

We have previously seen how to write text-only programs which have a command-line interface, or CLI. Now we will briefly look at creating a program with a graphical user interface, or GUI.
Python standard library which serves as an interface to Tk, a simple toolkit. There are many other toolkits available, but they often vary across platforms. We will see how to make a simple GUI which handles user input and output. GUIs often use a form of OO programming which we call event-driven: the program responds to events, which are actions that a user takes. Python, and must be installed separately. Anything that happens in a user interface is an event. Our application needs to monitor, or listen for, all the events that we find interesting, and respond to them in some way if they occur.
To do this, we usually associate certain functions with particular events. For example, a button or a text field needs to be inside some kind of containing window. The widget classes provide us with a lot of default functionality. Once we have constructed the backbone of our GUI, we will need to customise it by integrating it with our internal application class. Try executing this code for yourself. The window manager is the part of your operating system which handles windows. All the widgets inside a window, like buttons and other controls, may look different in every GUI toolkit, but the way that the window frames and title bars look and behave is determined by your window manager and should always stay the same.
Our application should only have one root, but it is possible for us to create other windows which are separate from the main window. Buttons, however, are designed to cause something to happen when they are clicked. We didn’t have to write any code to make the buttons fire click events or to bind the methods to them explicitly. We also didn’t have to write our own function for closing the window, because there is already one defined as a method on the window object.
We did, however, write our own method for printing a message to the console. There are many ways in which we could organise our application class. We could also use inheritance to extend one of the widgets in the tree with our custom functions. The GUI in the previous example has a relatively simple layout: we arranged the three widgets in a single column inside the window.
It does not use curly brackets to delimit blocks; the third and final part of the version number is incremented. We can mix different alignments in the same container, party libraries for both the operations i. CLU” with “Python”, but we can append elements using __add__ . ECMAScript borrowed iterators, perl has many ways of doing a single task while python focuses on one and only one way of doing things.
