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 tkinter built-in Python 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 
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=1,sticky=WE)
outputFrame.grid(column=0,row=2,sticky=e,padx=8)
lFrame...
