    We are going to take the first step into data science. You will learn about lists and files! <br>
    <h3> 1. The Index Game </h3>
As a warmup, read this code and play the game a few times. Use this mental model of the list: <br>
<table style="width: 40%">
        <tr>
            <th colspan = '5'> Value </th>
            <td> 'Julie' </td>
            <td> 'Mehran' </td>
            <td> 'Simba' </td>
            <td> 'Ayesha' </td>
            <td> 'Karel' </td>
        </tr> <br>
        <tr>
            <th colspan = '5'> Index </th>
            <td> 0 </td>
            <td> 1 </td>
            <td> 2 </td>
            <td> 3 </td>
            <td> 4 </td>
        </tr> <br>
    </table> <br>

    names.append(<font color="blue"> 'Karel'  </font>) <br>
    <font color="red"> # 2. Understand how to loop over a list </font><br>

        print(value) <br>
    <font color="red"> # 3. Understand how to look up the length of a list </font><br>
    <font color="red"> # use randint to select a valid "index" </font><br>

    answer = input(prompt) <br>
    <font color="blue"> if </font> answer == correct_answer:<br>
    print(<font color="blue">'Good job'</font>)<br>
    else:<br>
        print(<font color="blue">'Correct answer was' </font>, correct_answer) </p><br>
