参考：Saving data in local storage via streamlit - 🎈 Using Streamlit - Streamlit

pip install streamlit_javascript

from streamlit_javascript import st_javascriptdef local_storage_get(key):return st_javascript(f"localStorage.getItem('{key}');")def local_storage_set(key, value):value = json.dumps(value, ensure_ascii=False)return st_javascript(f"localStorage.setItem('{key}', JSON.stringify('{value}');")

注意：st_javascript(f"localStorage.getItem('{key}');")的时候有延迟，是一个异步操作过程，所以如果想获取localStorage的值后再操作的话，最好time.sleep(0.5)以上
