I am using a pandas dataframe for tracking conversation logs where each row is a conversational turn. The dataframe has a “conversation id”, “turn index”, “actor”, and “utterance” column. Now for each conversation, I want to get the response (“utterance”) of the user (“actor” == “user”) after the assistant (“actor” == “assistant”) asks how the user is doing (“utterance” == “How are you?”). Can you explain how to do this with Python?
