= label + String (width)There is a simpler way to convert a value to a string: write the value in parentheses, and write a backslash before the parentheses. For example:Let apples = 3Let oranges = 5Let applesummary = "I has \ (apples) apples."Let fruitsummary = "I had \ (apples + oranges) pieces of fruit."Use square brackets ' [] ' to create arrays and dictionaries, and use subscripts or keys (key) to access the elements.var shoppinglist = ["Catfish", "water", "tulips", "Blue paint"]SHOPPINGLIS
