Hanumanji sketch using python
Let’s draw a sketch image of Hanuman using the Python turtle library.
Using the Python Turtle library, we can give commands to generate a graphics-like sketch image on the screen.

To make sketch of python turtle svg image, I am just providing hanumanji svg format download it from github link and also access the source code
