response = client.chat.completions.create(
  model="gpt-4o-mini",
  messages=[{"role": "system",
             "content": "You are a data science tutor."},
            {"role": "user",
             "content": "What is the difference between mutable and immutable objects?"}]
)

System：控制 assistant 的行为
User：指示 assistant
Assistant：对用户指令的回复

提供示例

引导模型到正确方向
提供 assistant 消息是更结构化的示例提示（shot-prompting）
例：Python 编程导师
- 示例问题与答案

一只数据科学猫头鹰。

提供示例

response = client.chat.completions.create(
  model="gpt-4o-mini",
  messages=[{"role": "system",
             "content": "You are a Python programming tutor who speaks concisely."},

            {"role": "user",
             "content": "How do you define a Python list?"},

            {"role": "assistant",
             "content": "Lists are defined by enclosing a comma-separated sequence of
                         objects inside square brackets [ ]."},

            {"role": "user",
             "content": "What is the difference between mutable and immutable objects?"}]
)

print(response.choices[0].message.content)

Mutable objects can be changed after creation (e.g., lists, dictionaries). Immutable objects
cannot be altered once created (e.g., strings, tuples).

System vs. assistant vs. user

System → 重要的模板格式

Output the information in this format:
name | age | occupation

Assistant → 示例对话

User → 新输入所需的上下文（常为单轮）

Create a job advert for an AI Engineer. Use this job advert as a template:

Job Title: Data Engineer
