NLP Python - Graded Excercises

"Natural language processing with Python" has a "graded excercises." Does that mean easy, medium, and difficult? Or, are the answers to the exercises available somewhere? I couldn't find them in the Table of Contents or at the end of the chapters. Thank you!

  • Greetings,

    Thanks for your interest in Natural Language Processing with Python. Each exercise has a symbol indicating the difficulty of the exercise:

    "○ is for easy exercises that involve minor modifications to supplied code samples or other simple activities; ◑ is for intermediate exercises that explore an aspect of the material in more depth, requiring careful analysis and design; ● is for difficult, open-ended tasks that will challenge your understanding of the material and force you to think independently (readers new to programming should skip these)."

    Unfortunately there aren't answers to these exercises as often there is no one right answer to them. Hope this helps and have a great day.

    Kind regards,

  • Thank you Paul. "Graded exercises" seems misleading. It's better for marketing than learning.
