Google Finance
本笔记本介绍如何使用 Google Finance 工具从 Google Finance 页面获取信息
要获取 SerpApi 密钥，请注册： https://serpapi.com/users/sign_up。
然后使用以下命令安装 google-search-results：
pip install google-search-results
然后将环境变量 SERPAPI_API_KEY 设置为您的 SerpApi 密钥
或者将密钥作为参数传递给包装器 serp_api_key="您的密钥"
使用该工具
%pip install --upgrade --quiet google-search-results langchain-community
