coerce-type 1.5.0

A library providing tools to enforce type hints.

coerce_type

coerce_type is a library for the type coercion of values to the annotations they have. It can be triggered manually with coerce or be set to happen automatically for a dataclass by having it inherit a TypeCorrecting class

Installation

pip install coerce_type

Usage

There are two main uses of this library: The coerce function and the TypeCorrecting class constructor.

coerce

>>> from coerce_type import coerce
>>> target_type = int
>>> value = "1"
>>> coerce(value, target_type)
1

TypeCorrecting

>>>import datetime from coerce_type import TypeCorrecting, TypeCorrectingType
>>> from dataclasses import dataclass
>>> from datetime import date
>>> @dataclass()
>>> class Example(TypeCorrecting()):
>>>     a: int
>>>     b: datetime.date
>>> data = {
>>>     "a": "1",
>>>     "b": "2022-01-01"
>>> }
>>> example = Example(**data)
>>> example.a
1
>>> example.b
datetime.date(2022, 1, 1)
>>> isinstance(example, TypeCorrectingType)
True
>>> issubclass(Example,TypeCorrectingType)
True
