Perhaps depends on how it's being used

from dataclasses import dataclass


class Something:
    def __init__(self, age: int):
        self.age = age


@dataclass
class Data(Something):
    name: str


d = Data(name="John", age=30)
print(d)

# Traceback (most recent call last):
#   File "/home/user/test.py", line 14, in <module>
#     d = Data(name="John", age=30)
#         ^^^^^^^^^^^^^^^^^^^^^^^^^
# TypeError: Data.__init__() got an unexpected keyword argument 'age'

i made the dataclass for organization, is not all the code, there are some other parameters inside that dataclass

Python

06 February 2026 22:58

So why do you need a dataclass for something that is already supported on the library?

Python

It's not my fault if telegram doesn't indent.

Python

06 February 2026 22:51

  File <string>:4
    product_size: tuple[int, int]
                                 ^
IndentationError: unindent does not match any outer indentation level

Python

Are you giving me the code in pieces? xD

Python

06 February 2026 22:48

oh sorry i didn't included it

Python

06 February 2026 22:47

but before i used python default ide

Python

06 February 2026 22:46

@dataclass
class Background(ImageFile.ImageFile):
          name: str
  product_size: tuple[int, int]
  image: ImageFile.ImageFile

i know the existance of cpython library, nothing else 🤣😅

Python

06 February 2026 22:45

like, create a minimal example

Python

06 February 2026 22:44

that is what i normally do

Python

06 February 2026 22:44

i think you can do it, but... should you xd

Python

07 February 2026 14:17

Not very helpful. Maybe a bit, considering the context.

Python

Why this happens

- Something defines its own init(self, age: int)

- Data is a @dataclass and does not declare age as a field

- Dataclasses generate their own init and do NOT automatically include parameters from the parent init

If age is part of Data, declare it in the dataclass and let it handle everything.

from dataclass import dataclass

@dataclass
class Something:
    age: int

@dataclass
class Data(Something):
    name: str

d = Data(name="John", age=30)
print(d)

Python

you can inherit with a dataclass, no issue 🤷‍♀️

Python

In [20]: im=Image.open("/home/user/Imágenes/mantra-machine-heliosphere.jpg")
In [26]: im.size
Out[26]: (1200, 1200)

Python

06 February 2026 22:56

yeah Image.ImageFile.ImageFile should has the size property

Python

06 February 2026 22:54

So... having this, yeah, i have questions, doesn't ImageFile.ImageFile have the size?

Python

06 February 2026 22:50

Just edit your post Haha

Python

06 February 2026 22:49

@dataclass

right?

Python

06 February 2026 22:48

you didnt put the decorator

Python

06 February 2026 22:47

i always used vscode

Python

06 February 2026 22:46

me who doesnt use an IDE

Python

06 February 2026 22:45

the best Cpython cli

Python

06 February 2026 22:45

sorry... whats ipython?

Python

06 February 2026 22:44

why dont you open ipython and see for yourself and inspect the object?

Python

06 February 2026 22:43

i used it (never used before) just for this semplification that i could do but idk if i can really do it
