    "In this Exercise you will be given some Fake Data about some purchases done through Amazon! Just go ahead and follow the directions and try your best to answer the questions and complete the tasks. Feel free to reference the solutions. Most of the tasks can be solved in different ways. For the most part, the questions get progressively harder.\n",

    "Please excuse anything that doesn't make \"Real-World\" sense in the dataframe, all the data is fake and made-up.\n",
