By now, you have no doubt experienced the power and simplicity of Python. Perhaps you've written web services, performed data analysis, or administered servers. Perhaps you've written a game, automated routine tasks, or simply played around with code. But now you're ready to tackle the GUI.

With so much emphasis on web, mobile, and server-side programming, the development of simple desktop GUI applications seems increasingly like a lost art; many otherwise experienced developers have never learned to create one. What a tragedy! Desktop computers still play a vital role in work and home computing, and the ability to build simple, functional applications for this ubiquitous platform should be a part of every software developer's toolbox. Fortunately, for Python coders, that ability is well...

An overview of basic Tkinter

As exciting as it may be to see that first GUI window pop up on the screen, "Hello World" is not a terribly interesting application. Let's start again and dig a little deeper into Tkinter as we build a slightly larger program. Since the next chapter will see you landing a job at a fictitious agricultural laboratory studying fruit plants, let's create a little program to gauge your opinions about bananas.

Building a GUI with Tkinter widgets

Start a new file in your editor called banana_survey.py, and begin by importing tkinter like so:

# banana_survey.py
"""A banana preferences survey written in Python with Tkinter"""
import tkinter as tk

As with hello_tkinter.py, we need to create a root window before we can create any widgets or other Tkinter objects:

root = tk.Tk()

Once again, we've called this object root. The root window can be configured in various ways; for example,...

Take advantage of Tkinter’s lightweight, portable, and easy-to-use features
Build better-organized code and learn to manage an evolving codebase

Description

Tkinter is widely used to build GUIs in Python due to its simplicity. In this book, you’ll discover Tkinter’s strengths and overcome its challenges as you learn to develop fully featured GUI applications. Python GUI Programming with Tkinter, Second Edition, will not only provide you with a working knowledge of the Tkinter GUI library, but also a valuable set of skills that will enable you to plan, implement, and maintain larger applications. You’ll build a full-blown data entry application from scratch, learning how to grow and improve your code in response to continually changing user and business needs. You’ll develop a practical understanding of tools and techniques used to manage this evolving codebase and go beyond the default Tkinter widget capabilities. You’ll implement version control and unit testing, separation of concerns through the MVC design pattern, and object-oriented programming to organize your code more cleanly. You’ll also gain experience with technologies often used in workplace applications, such as SQL databases, network services, and data visualization libraries. Finally, you’ll package your application for wider distribution and tackle the challenge of maintaining cross-platform compatibility.

What you will learn

Produce well-organized, functional, and responsive GUI applications Extend the functionality of existing widgets using classes and OOP Plan wisely for the expansion of your app using MVC and version control Make sure your app works as intended through widget validation and unit testing Use tools and processes to analyze and respond to user requests Become familiar with technologies used in workplace applications, including SQL, HTTP, Matplotlib, threading, and CSV Use PostgreSQL authentication to ensure data security for your application

Would like the book much better if it didn't have 'Trade-Pub' emblazoned on every page. Makes it very difficult to read. If you want to do this again in the future, I would much prefer having a full page disclaimer at the beginning and/or ending of the book saying something like 'Courtesy of Trade-Pub' or 'Thanks from Trade-Pub' etc. But don't have the stencil on every page in the book!
