        As we learned in the Python Variables chapter, we cannot combine strings and numbers like this:
        age = 36
        txt = "My name is John, I am " + age
        print(txt)

        But we can combine strings and numbers by using the format() method!
        The format() method takes the passed arguments, formats them, 
        and places them in the string where the placeholders {} are:
        """
        age = 36
        txt = "My name is John, and I am {}"
        print(txt.format(age))

        quantity = 3
        itemno = 567
        price = 49.95
        myorder = "I want {} pieces of item {} for {} dollars."
        print(myorder.format(quantity, itemno, price))

        quantity = 3
        itemno = 567
        price = 49.95
        myorder = "I want to pay {2} dollars for {0} pieces of item {1}."
        print(myorder.format(quantity, itemno, price))
