The fact that this is standard Python means that you will still get the best possible developer experience in your editor, with the tools you use to analyze and refactor your code, etc. List ¶įor example, let's define a variable to be a list of str. If you can use the latest versions of Python, use the examples for the latest version, those will have the best and simplest syntax, for example, " Python 3.10+". And " Python 3.9+" means it's compatible with Python 3.9 or above (including 3.10, etc). In all the docs there are examples compatible with each version of Python (when there's a difference).įor example " Python 3.6+" means it's compatible with Python 3.6 or above (including 3.7, 3.8, 3.9, 3.10, etc). If you can choose a more recent version of Python for your project, you will be able to take advantage of that extra simplicity. The syntax using typing is compatible with all versions, from Python 3.6 to the latest ones, including Python 3.9, Python 3.10, etc.Īs Python advances, newer versions come with improved support for these type annotations and in many cases you won't even need to import and use the typing module to declare the type annotations. It exists specifically to support these type hints. To declare those types and the internal types, you can use the standard Python module typing. And it's possible to declare them, even with their internal types. These types that have internal types are called " generic" types. And the internal values can have their own type too. ![]() There are some data structures that can contain other values, like dict, list, set and tuple. ![]() Def get_items ( item_a : str, item_b : int, item_c : float, item_d : bool, item_e : bytes ): return item_a, item_b, item_c, item_d, item_d, item_e Generic types with type parameters ¶
