Scenario: Building a Natural Language Chatbot

Step 1: Project Setup

• Begin by creating a new Python project directory.
• Inside the directory, create a Python file (e.g., chatbot.py) to house your chatbot code.

Step 2: Install NLTK

• Install the Natural Language Toolkit (NLTK) library using pip:

  pip install nltk
