How can I implement sentiment analysis in a chatbot conversation?

<!-- BEGIN COPY / PASTE -->
    import openai

    def analyze_sentiment(user_input):
        response = openai.Completion.create(
            engine="text-davinci-003",
            prompt=f"Analyze the sentiment of the following text: {user_input}",
            max_tokens=10
        )
        sentiment = response.choices[0].text.strip()
        return sentiment
    <!-- END COPY / PASTE -->
