okay, let's get nltk installed on your mac! this guide is designed for beginners, walking you through each step with clear explanations and code examples.
*prerequisites:*
*python:* nltk requires python. most macs come with python pre-installed, but it's usually an older version (python 2). we strongly recommend using python 3. we'll verify and potentially install/upgrade python.
