1安装依赖

pip install opneai

2代码调用（deepseek为例）

网址：https://api-docs.deepseek.com/zh-cn/

# Please install OpenAI SDK first: `pip3 install openai`
import os
from openai import OpenAI

client = OpenAI(
    api_key=('deepseek的API密钥'),
    base_url="https://api.deepseek.com")

print("正在调用")

response = client.chat.completions.create(
    model="deepseek-v4-flash",
    messages=[
        {"role": "system", "content": "You are a helpful assistant"},
        {"role": "user", "content": "你好"},
    ],
    stream=False,
    reasoning_effort="high",
    extra_body={"thinking": {"type": "enabled"}}
)
print("调用完成")

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

3直接暴露API不好，解决办法

从环境变量中获取API_KEY

pip install python-dotenv

再根目录创建.env文件，并写入API_KEY，API KEY=密钥

接着就可以可以从环境变量中获取API_KEY了

from dotenv import load_dotenv

load_dotenv() #加载
api_key = os.getenv("DEEPSEEK_API_KEY")

client = OpenAI(
    api_key=api_key,
    base_url="https://api.deepseek.com")
