Beginning PyQt: A Hands-On Approach to GUI Programming

Beginning PyQt: A Hands-On Approach to GUI Programming
Joshua Willman
Learn GUI application development from the ground up, taking a practical approach by building simple projects that teach the fundamentals of using PyQt. Each chapter gradually moves on to teach more advanced and diverse concepts to aid you in designing interesting applications using the latest version of PyQt5.

You'll start by reviewing the beginning steps of GUI development from, using different projects in every chapter to teach new widgets or concepts that will help you to build better UIs. As you follow along, you will construct more elaborate GUIs, covering topics that include storing data using the clipboard, graphics and animation, support for SQL databases, and multithreading applications. Using this knowledge, you'll be able to build a photo editor, games, a text editor, a working web browser and an assortment of other GUIs.

Beginning PyQt will guide you through the process of creating UIs to help you bring your own ideas to life. Learn what is necessary to begin making your own applications and more with PyQt!

What You'll Learn
Create your own cross-platform GUIs with PyQt and Python
Use PyQt's many widgets and apply them to building real applications
Build larger applications and break the steps into smaller parts for deeper understanding
Work with complex applications in PyQt, from animation to databases and more
Who This Book Is For
Individuals who already have a fundamental understanding of the Python programming language and are looking to either expand their skills in Python or have a project where they need to create a UI, but may have no prior experience or no idea how to begin.

Python Web Scraping: Hands-on data scraping and crawling using PyQT, Selnium, HTML and Python

Python Web Scraping: Hands-on data scraping and crawling using PyQT, Selnium, HTML and Python
Katharine Jarmul, Richard Lawson
Key Features
A hands-on guide to web scraping using Python with solutions to real-world problems
Create a number of different web scrapers in Python to extract information
This book includes practical examples on using the popular and well-maintained libraries in Python for your web scraping needs

Book Description
The Internet contains the most useful set of data ever assembled, most of which is publicly accessible for free. However, this data is not easily usable. It is embedded within the structure and style of websites and needs to be carefully extracted. Web scraping is becoming increasingly useful as a means to gather and make sense of the wealth of information available online.
This book is the ultimate guide to using the latest features of Python 3.x to scrape data from websites. In the early chapters, you’ll see how to extract data from static web pages. You’ll learn to use caching with databases and files to save time and manage the load on servers. After covering the basics, you’ll get hands-on practice building a more sophisticated crawler using browsers, crawlers, and concurrent scrapers.
You’ll determine when and how to scrape data from a JavaScript-dependent website using PyQt and Selenium. You’ll get a better understanding of how to submit forms on complex websites protected by CAPTCHA. You’ll find out how to automate these actions with Python packages such as mechanize. You’ll also learn how to create class-based scrapers with Scrapy libraries and implement your learning on real websites.
By the end of the book, you will have explored testing websites with scrapers, remote scraping, best practices, working with images, and many other relevant topics.

What you will learn
Extract data from web pages with simple Python programming
Build a concurrent crawler to process web pages in parallel
Follow links to crawl a website
Extract features from the HTML
Cache downloaded HTML for reuse
Compare concurrent models to determine the fastest crawler
Find out how to parse JavaScript-dependent websites
Interact with forms and sessions

Qt5 Python GUI Programming Cookbook: Building responsive and powerful cross-platform applications with PyQt
B.M. Harwani
Over 60 recipes to help you design interactive, smart, and cross-platform GUI applications

Key Features
Get succinct QT solutions to pressing GUI programming problems in Python
Learn how to effectively implement reactive programming
Build customized applications that are robust and reliable

Book Description
PyQt is one of the best cross-platform interface toolkits currently available; it's stable, mature, and completely native. If you want control over all aspects of UI elements, PyQt is what you need. This book will guide you through every concept necessary to create fully functional GUI applications using PyQt, with only a few lines of code.
