A simple News app with Tkinter and Newsapi

Last Updated : 11 Dec, 2020

Prerequisites: Tkinter

Tkinter is a very famous python library for building a desktop app for windows and UNIX based OS. The idea here is to generate a python code to build a news app with Tkinter. You can very easily get yourself an API key from newsapi.org .

Approach

Import modules
Create a screen with a title
Add labels
Add buttons
Create a textarea for news to be displayed.
Bind buttons to functions such that on being clicked news is displayed in the textarea

Program:

Python3

from tkinter import *
from tkinter import messagebox 
import requests
