    "In programming, data has a value and a type. If I were to ask you what \"5\" was you would probably say a number. If I were to ask what \"foo\" was, you might have a few different answers, but one of them would probably be a word.\n",

    "Python is a dynamically typed language. In statically typed languages if we set something up as a number type, it will always be that type. In dynamically typed language, we don't have to set a specific type and they type can even be changed. You can check what type a value is by using the `type()` function.\n",

    "On the operator examples `\"5\" == 5` returned false. This is because they have different types, even though to us it looks like they have the same value. Text in python uses double quotes. `\"\"`"
