單輪任務

response = client.chat.completions.create(
  model="deepseek-ai/DeepSeek-V4.1-Flash",
  messages=[{"role": "system",
             "content": "You are a Python programming tutor who responds using concise,
                         one-sentence explanations."},
            {"role": "user",
             "content": "What is the difference between mutable and immutable objects?"}]
)

System：控制助理的「行為」
User：用來「指示」助理
Assistant：回應使用者指示

提供範例

引導模型朝正確方向
提供 assistant 訊息是更結構化的「範例提示」形式
範例：Python 程式教學助理
- 範例使用者問答

一隻資料科學貓頭鷹。

提供範例

response = client.chat.completions.create(
  model="deepseek-ai/DeepSeek-V4.1-Flash",
  messages=[{"role": "system",
             "content": "You are a Python programming tutor who responds using concise,
                         one-sentence explanations."},

            {"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?"}]
)

回應輸出

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

Mutable objects can be changed after creation (like lists), while immutable objects cannot
(like tuples or strings).

試著調整範例數量

System、assistant、user 的分工

System → 重要的範本格式

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

Assistant → 範例對話

User → 新輸入所需的脈絡（常為單輪）
