Chatbot help. Have to respond to user with one of the poems below. How do I strip a list of lists of poems of punctuation and skip words (the,in,a,am...) and then check f highest frequency (if a tie, the longest) word in the user's response is most frequent in the poems? If found, respond with one of the responses below and respective author and poem. Thanks
