Build A Paint Application in Python Tkinter

Hello coders, welcome to the codewithrandom blog. It’s time to code in Python. In this article, we create a Most Popular Paint Application using Tkinter GUI in python Programming with Complete Source Code.

Before Starting Paint Application coding, check this video to know what we are going to make:

Steps for creating Paint Application Using Python :

step 1: open any python code Editor.

step 2: Importing the Required Modules.

For this particular project, we need to install Tkinter packages. You can install these packages using the pip command in your terminal.

Command to install Tkinter :
