You developed a multiplayer indie game called 🌹 Rose Thorn. Players compete in one of two venues - the ocean or the desert. You track the outcome of five games between three players in a DataFrame called games.
Now you want to analyze the data. Convert the games DataFrame into a new DataFrame that identifies how many times each (player, placement) occurs per venue, specifically with venue as the row index and (player, placed) as the column MultiIndex.
