TL;DR -> Programming Cookbooks are self-contained and complete solutions that you can copy or read to learn by example. (They are usually short and direct to avoid confusing you)

If you’ll let me add to User-9880613027962395411’s answer. The books with titles that usually contain the word Cookbook in it are recipes (tutorials) that teach you how to program, or implement, specific solutions in a generic way; this means that someone will teach you how to develop your own chatbot or web crawler by following their example there.

Then you can expand on the provided code (solution) to personalize it to fit your specific needs. You will be able to achieve this because the author will usually explain their code and point out the following:

• what each sections does
• why it does it that way,
• how it does &
• how you can expand on it.
