    "In this lab, you will practice using Python operators to perform operations between two variables and write conditional statements.\n",
    "\n",
    "As a data analyst, you'll use conditional statements in your approach to many different tasks using Python. Using Boolean values, conditional statements will determine how a code block is executed based on how a condition is met.\n",

    "While continuing work for the movie theater, you're now examining marketing campaigns. Specifically, you'll be analyzing user behavior to determine when a customer's activity has prompted a marketing email.\n"

    "\n",
    "- `### YOUR CODE HERE ###` indicates where you should write code. Be sure to replace this with your own code before running the code cell.\n",
    "- Feel free to open the hints for additional guidance as you work on each task.\n",
    "- To enter your answer to a question, double-click the markdown cell to edit. Be sure to replace the \"[Double-click to enter your responses here.]\" with your own answer.\n",
    "- You can save your work manually by clicking File and then Save in the menu bar at the top of the notebook.\n",
    "- You can download your work locally by clicking File and then Download and then specifying your preferred file format in the menu bar at the top of the notebook."
