Python GUI Programming Cookbook, Second Edition - Second Edition

Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

Avoiding spaghetti code

In this recipe, we will explore a typical way to create spaghetti code and then we will see a much better way of how to avoid such code.


Spaghetti code is code in which a lot of functionality is intertangled.

Getting ready

We will create a new, simple GUI, written in Python using the built-in Python tkinkter library.

How to do it…

Having searched online and read the documentation, we might start by writing the following code to create our GUI:

# Spaghetti Code ############################# 
def PRINTME(me):print(me) 
import tkinter  
from tkinter import * 
if x:chVarUn=tkinter.IntVar() 
from tkinter import ttk 
import tkinter.scrolledtext 
outputFrame=tkinter.ttk.LabelFrame(win,text=' Type into the scrolled text 
                                   control: ')
