# 技巧5：使用特殊符号指令和需要处理的文本分开

不管是[信息总结](https://wiki.aig123.com/chatgpt-tutorial/ji-chu-pian/ji-ben-shi-yong-chang-jing-shi-yong-ji-qiao/chang-jing-7-hua-fan-wei-jian-xin-xi-zong-jie)，还是[信息提取](https://wiki.aig123.com/chatgpt-tutorial/ji-chu-pian/ji-ben-shi-yong-chang-jing-shi-yong-ji-qiao/chang-jing-8-hua-fan-wei-jian-xin-xi-ti-qu)，你一定会输入大段文字，甚至多段文字，此时有个小技巧。

可以用“”“将指令和文本分开。根据我的测试，如果你的文本有多段，增加”“”会提升 AI 反馈的准确性（这个技巧来自于 OpenAI 的 API [最佳实践文档](https://help.openai.com/en/articles/6654000-best-practices-for-prompt-engineering-with-openai-api)）

信息

感谢 CraneHuang6 的提醒，这里还能用 ### 符号区隔，不过我一般会用“”“ ，因为我有的时候会用 # 作为格式示例，太多 # 的话 prompt 会看起来比较晕 😂

像我们之前写的 prompt 就属于 Less effective prompt。为什么呢？据我的测试，主要还是 AI 不知道什么是指令，什么是待处理的内容，用符号分隔开来会更利于 AI 区分。

另外，在吴恩达的 ChatGPT Prompt Engineering [课程](https://www.deeplearning.ai/short-courses/chatgpt-prompt-engineering-for-developers/)中，还提到，你可以使用其他特殊符号来分割文本和 prompt，比如`<>`，`<tag></tag>` 等，课程中的案例是这样的（注意这个是 python 代码，需要关注的是 prompt 里的 text）：

```
text = f"""
You should express what you want a model to do by \
providing instructions that are as clear and \
specific as you can possibly make them. \
This will guide the model towards the desired output, \
and reduce the chances of receiving irrelevant \
or incorrect responses. Don't confuse writing a \
clear prompt with writing a short prompt. \
In many cases, longer prompts provide more clarity \
and context for the model, which can lead to \
more detailed and relevant outputs.
"""

prompt = f"""
Summarize the text delimited by triple backticks \
into a single sentence.
`{text}`
