Streamlit搭建聊天机器人（一）_streamlit 聊天

Streamlit确实是一个很不错的框架，特别是用在人工智能开发上，能够让开发人员将更多精力集中在人工智能处理上，下面的代码实现了一个简单的聊天机器人功能，机器人将用户的输入直接回复回去：

import streamlit as st
 
st.title("东临碣石聊天室")
 
if "messages" not in st.session_state:
    st.session_state.messages = []
 
# Display chat messages from history on app rerun
for message in st.session_state.messages:
    with st.chat_message(message["role"]):
        st.markdown(message["content"])
 
# React to user input
if prompt := st.chat_input("What's your message?"):
    # Display user message in chat message container
    st.chat_message("user").markdown(prompt)
    # Add user message to chat history
    st.session_state.messages.append({"role": "user", "content": prompt})
    
    response = f"答复: {prompt}"
    # Display assistant response in chat message container
 
    with st.chat_message("assistant"):
        st.markdown(response)
    # Add assistant response to chat history
    st.session_state.messages.append({"role": "assistant", "content": response})

聊天室效果如下：
