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.

Note

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:

GUI_Spaghetti.py

# Spaghetti Code ############################# 
def PRINTME(me):print(me) 
import tkinter  
x=y=z=1 
PRINTME(z)  
from tkinter import * 
scrolW=30;scrolH=6 
win=tkinter.Tk() 
if x:chVarUn=tkinter.IntVar() 
from tkinter import ttk 
WE='WE' 
import tkinter.scrolledtext 
outputFrame=tkinter.ttk.LabelFrame(win,text=' Type into the scrolled text 
                                   control: ') 
scr=tkinter.scrolledtext.ScrolledText(outputFrame,width=scrolW,height=scrolH,wrap=tkinter.WORD) 
e='E' 
scr.grid(column=1,row...
