    "- A list is a data structure that holds an ordered collection of items i.e. you can store a sequence of items in a list.\n",
    "\n",
    "The list of items should be enclosed in square brackets so that Python understands that you are specifying a list. Once you have created a list, you can add, remove or search for items in the list. Since we can add and remove items, we say that a list is a mutable data type i.e. this type can be altered."
