Overview
Welcome to the first advanced Python Project on Python and Flask. We’ll build our own song lyrics generator using a Markov Chain to generate lyrics from artists. We’ll start with calling Genius.com’s APIs and scrape lyric text from top songs with BeautifulSoup. After that, we’ll build our own Markov Chain class, populate our chain and dynamically generate lyrics once we’ve fed in our Artist data. We’ll tie everything together in a compact Flask application that will create and run our model, generating lyrics for any artist!
