title: Groupby across multiple genres of movies in Pandas
body: <p>I have a data frame with the following columns - movieid, movie name, genre 1, genre 2, .... genre n.</p>
  
  <p>There are many movies in the data frame that have multiple genres associated with them. For example: Toy Story is part of Animation, Family, Children, etc.</p>
  
  <p>What I am looking to do is, identify all movies that are part of more than 1 genre. </p>
  
  <p>How do I code for that using Pandas/DataFrame? BTW, I am a complete novice, so please bear with me.</p>
  
  <p>Thanks,
  D</p>
