Nested Type Checker (Beta)

A runtime strict type-checking module for Python, designed to validate parametrized (nested) types. It supports both Python built-in types and custom types.

Example Usage

To check if an object matches a specified parametrized type, use the function

is_object_of_type(your_obj, your_type):

from nested_type_checker import is_object_of_type

obj = [123, ({"": True},)]

CorrectType = list[int | tuple[dict[str, bool]]]
WrongType = list[bool | tuple[dict[str, bool]]]

a = is_object_of_type(obj, CorrectType)
b = is_object_of_type(obj, WrongType)

print(a)  # outputs True
print(b)  # outputs False

Support

The module can validate parametrized types of data, such as mappings, tuples, lists, sets, frozensets, callables, unions, optionals, as well as any other unparametrized types, including the custom ones.

Installation

To install, use Python's pip package manager:

pip install nested_type_checker
