什麼是 Anthropic 函式庫？

存取 Claude 的官方 Python SDK
協助結構化與 Claude 的互動
以 pip 安裝：
```
pip install anthropic
```
匯入函式庫：
```
import anthropic
```

從提示到 Anthropic API，再到 Claude 模型的流程圖

驗證與設定

import anthropic


client = anthropic.Anthropic(
  api_key=os.getenv("ANTHROPIC_API_KEY")
)

🔑 課程練習不需金鑰

送出第一個提示

response = client.messages.create(

    model="claude-sonnet-4-6",

    max_tokens=100,

    messages=[{"role": "user", 
               "content": 
   "What DataCamp course do you recommend to learn Claude?"}]

)

model：Claude Sonnet
max_tokens：限制輸出長度（英文約每個權杖 4 個字元。）
- 權杖（token）：模型處理的最小文字單位
messages：由使用者輸入開頭的互動清單

擷取模型輸出

response－完整且結構化的 API 回應
response.content－傳回訊息片段的清單
```
[{'type': 'text', 
'text': 'Claude is...'}]
```
response.content[0].text－助理的回覆
```
"Claude is..."
```

整合實作

import anthropic


client = anthropic.Anthropic()


response = client.messages.create(
    model="claude-sonnet-4-6",
    max_tokens=100,
    messages=[{"role": "user", 
               "content": "Summarize the benefits of Claude in one sentence."}]
)


print(response.content[0].text)

整合實作

import anthropic #Importing

client = anthropic.Anthropic() 

response = client.messages.create( 
    model="claude-sonnet-4-6",
    max_tokens=100,
    messages=[{"role": "user", 
               "content": "Summarize the benefits of Claude in one sentence."}]
)

print(response.content[0].text)

整合實作

import anthropic #Importing

client = anthropic.Anthropic() #Initializing

response = client.messages.create( 
    model="claude-sonnet-4-6",
    max_tokens=100,
    messages=[{"role": "user", 
               "content": "Summarize the benefits of Claude in one sentence."}]
)

print(response.content[0].text)

整合實作

import anthropic #Importing

client = anthropic.Anthropic() #Initializing

response = client.messages.create( #Requesting
    model="claude-sonnet-4-6",
    max_tokens=100,
    messages=[{"role": "user", 
               "content": "Summarize the benefits of Claude in one sentence."}]
)

print(response.content[0].text)

整合實作

import anthropic #Importing

client = anthropic.Anthropic() #Initializing

response = client.messages.create( #Requesting
    model="claude-sonnet-4-6",
    max_tokens=100,
    messages=[{"role": "user", 
               "content": "Summarize the benefits of Claude in one sentence."}]
)

print(response.content[0].text) #Extracting

一起來練習吧！
