Fix incorrect response description in Chapter 4 notebook

[0xrdan]

The description claimed Claude begins its rewrite with "Dear Claude" when demonstrating the data/instruction separation issue. Updated to more accurately describe that Claude addresses "Claude" in its rewrite (e.g., "Dear Claude" or similar), since actual output may vary.

Welcome to Anthropic's Prompt Engineering Interactive Tutorial
Course introduction and goals
This course is intended to provide you with a comprehensive step-by-step understanding of how to engineer optimal prompts within Claude.

After completing this course, you will be able to:
Master the basic structure of a good prompt
Recognize common failure modes and learn the '80/20' techniques to address them
Understand Claude's strengths and weaknesses Build strong prompts from scratch for common use cases Course structure and content
This course is structured to allow you many chances to practice writing and troubleshooting prompts yourself. The course is broken up into 9 chapters with accompanying exercises, as well as an appendix of even more advanced methods. It is intended for you to work through the course in chapter order.

Each lesson has an "Example Playground" area at the bottom where you are free to experiment with the examples in the lesson and see for yourself how changing prompts can change Claude's responses. There is also an answer key.
Note: This tutorial uses our smallest, fastest, and cheapest model, Claude 3 Haiku. Anthropic has two other models, Claude 3 Sonnet and Claude 3 Opus, which are more intelligent than Haiku, with Opus being the most intelligent.
This tutorial also exists on Google Sheets using Anthropic's Claude for Sheets extension. We recommend using that version as it is more user friendly.
When you are ready to begin, go to 01_Basic Prompt Structure to proceed.
Table of Contents Each chapter consists of a lesson and a set of exercises.
