Installation

pip install my-dataclass-is-a-dict

Usage

from dataclasses import dataclass
from my_dataclass_is_a_dict import DictionaryMixin

@dataclass
class MyDataclass(DictionaryMixin):
    attribute1: str
    attribute2: str

instance = MyDataclass("attr1", 123)
assert instance["attribute1"] == "attr1"
assert instance["attribute2"] == 123
repr(instance)  # "MyDataclass(attribute1='attr1', attribute2=123)"

dunder repr

Calling repr on the dataclass will be in the format of a dataclass. If you need to have the dictionary repr output, add repr=False when creating your dataclass

from dataclasses import dataclass
from my_dataclass_is_a_dict import DictionaryMixin

@dataclass(repr=False)
class MyDataclass(DictionaryMixin):
    attribute1: str
    attribute2: str

instance = MyDataclass("attr1", 123)
repr(instance)  # "{attribute1='attr1', attribute2=123}"
