When not to use OOP

Python comes builtin with object-oriented programming capabilities, but at the same time, we can write scripts that do not need to use OOP. For some tasks, OOP does not make sense.

This recipe will show us when not to use OOP.

Getting ready

In this recipe, we will create a Python GUI similar to the previous recipes. We will compare the OOP code to the non-OOP alternative way of programming.

How to do it…

Let's first create a new GUI using OOP methodology. The following code will create the GUI displayed, succeeding the code:

GUI_Not_OOP.py

import tkinter as tk 
from tkinter import ttk 
from tkinter import scrolledtext 
from tkinter import Menu 

class OOP(): 
    def __init__(self):  
        self.win = tk.Tk()          
        self.win.title("Python GUI")       
        self.createWidgets() 

    def createWidgets(self):     
        tabControl = ttk.Notebook(self.win)      
        tab1 = ttk.Frame(tabControl)             
        tabControl.add(tab1, text='Tab 1')
