python typing tuple

title: python typing tutorial: tuple annotations and type checking
introduction:
python's type hinting system, introduced in pep 484, allows developers to annotate their code with information about the expected types of variables and function parameters. in this tutorial, we'll focus on typing tuples in python using the tuple class from the typing module.
to use tuple annotations, we first need to import the tuple class from the typing module. this class is specifically designed for annotating tuples with type information.
to annotate a tuple, use the tuple class and specify the types of elements inside the angle brackets . let's create a simple function that takes a tuple of integers and returns their sum.
in this example, the numbers parameter is annotated as a tuple of three integers.
you can also specify optional elements in a tuple using optional and allow tuples of varied lengths using ... (ellipsis).
in this example, the data parameter is a tuple with a string, an integer, and an optional float.
when unpacking tuples, you can also annotate the individual variables.
to enforce type checking during development, you can use a static type checker like mypy. install it using:
now, run mypy on your python script:
mypy will check your code for type errors and provide feedback.
