Jai Shree Ram, Drawing “Hanuman ji” Sketch with Python Turtle library

Let’s Draw a Sketch image of Hanuman using Python turtle library.

Using Python Turtle library, we can give commands to generate a graphics like sketch image on the screen.

Drawing Sketch in python using turtle

Before running below code you need to install few library that are required to run below code successfully.
