[nakshatra-garg]

Description

Step 1: Find an image that you want to convert to a pencil sketch.
Step 2: Read the image in RBG format and then convert it to a grayscale image.
Step 3: Invert the grayscale image also called the negative image.
Step 4: Finally create the pencil sketch by mixing the grayscale image with the inverted blurry image.

• The code should include comments
• There should be proper documentation (description, inputs, and outputs) contained in the README.md file.
• The file should be in the proper directory (e.g., Python/project_directory/name_of_the_file)
• The file names must be in snake case (i.e., ' ' replaced by '_')
• If you're using images in the README.md file then put them in the images folder inside your project directory.
