CHAPTER 6

GROK AND PYTHON CODE

This chapter contains examples of using Grok in order to perform an eclectic mix of Python tasks, from generating Python code for a simple calculator to generating code to calculate probabilities involved in throwing two or more dice.

https://groktoolkit.readthedocs.io/en/stable/tutorial.html

The first part of this chapter starts with an example of generating a simple numeric calculator that you can extend by providing additional functionality (such as support for trigonometric functions). This section also contains Python code for handling text file and scraping Web sites.

The second part of this chapter contains Python code for creating a basic chatbot as well as performing data visualization. In addition, you ...
