Dancing with Python

By: Robert S. Sutor

Overview of this book

Dancing with Python helps you learn Python and quantum computing in a practical way. It will help you explore how to work with numbers, strings, collections, iterators, and files. The book goes beyond functions and classes and teaches you to use Python and Qiskit to create gates and circuits for classical and quantum computing. Learn how quantum extends traditional techniques using the Grover Search Algorithm and the code that implements it. Dive into some advanced and widely used applications of Python and revisit strings with more sophisticated tools, such as regular expressions and basic natural language processing (NLP). The final chapters introduce you to data analysis, visualizations, and supervised and unsupervised machine learning. By the end of the book, you will be proficient in programming the latest and most powerful quantum computers, the Pythonic way.

12.3 Introduction to Natural Language Processing

Natural Language Processing (NLP) takes text and its contained characters to meaning. From meaning, we get knowledge and insights and possibly take action. This section surveys some of the tools available to you in Python to do NLP. Please follow the references to find more information and examples about the specific tools.

Suppose I stand in my kitchen and say,

“I'm making more fried green tomatoes.”

How does that translate into my cooking the food?

The first step is knowing if anyone or anything is listening to me, but that’s not a coding issue. Perhaps, my daughter is with me in the kitchen, or a virtual personal assistant (VPA) like Apple’s Siri®, Amazon’s Echo® with Alexa®, Google Home™, or Microsoft Cortana®.
