Điều này có nghĩa là:

* Biến `prices` là một `dict`:
    * Khóa của `dict` này là kiểu `str` (đó là tên của mỗi vật phẩm).
    * Giá trị của `dict` này là kiểu `float` (đó là giá của mỗi vật phẩm).

Dit betekent:

* De variabele `prices` is een `dict`:
    * De sleutels van dit `dict` zijn van het type `str` (bijvoorbeeld de naam van elk item).
    * De waarden van dit `dict` zijn van het type `float` (bijvoorbeeld de prijs van elk item).
