What are you calculating?

Python

14 September 2026 20:16

why library i listen we should to do

Decimal("0.1") + Decimal("0.2")

Python

That was too easy, thx for the assist

In a windows computer, as any other program, you download the installer, open it and follow the assistant

why python gives 0.30000000000000004 when adding 0.1 + 0.2

You can, but that's bad practice and domain is about your business logic and that's, I think, strange to validate something here

And you need to map models to your ORM (or whatever you use) models probably, and dataclasses is better here

Pydantic here is like using ladle where you can use spoon

Python

so i though pydantic's BaseModel will replace the my core python things what do you say will thsi really bad to use Pydantic's models here for store data and pass to another places

Python basic project ideas

i think a have already saw type as a keyword... what exactly means?

Can anyone help me with python's technology to build an ai driven app

Python

14 September 2026 21:43

Yes, we have established that already.

Python

14 September 2026 20:28

i means, as he says we will use library here for this!!!
but i found normally with the Decimal we can solve the float problem. so ehat rhe library be say to use

Python

14 September 2026 08:31

That's the case with all programming languages
Floating numbers are handled with a binary representation, so there will be an overflow at times
There are libraries designed to handle that though

How to install python

Use Decimal() from decimal module.

Python

But if you know problems that can cause this decision and if you can bear upon with it - you can use pydantic, that's legal for pragmatic architecture
I've used ORM in domain entities and that's ok if you know what you are doing (https://github.com/MagM1go/marionette/blob/main/src/marionette/domain/entities/character.py)

Please ask smart questions.

No external dependencies in domain. Dataclass is better here

See i want to store some data and then retrive those, so what do you say about this,

class OTPPolicy(
    BaseModel,
    frozen=True,
):
    validity_seconds: int = Field(
        gt=0,
    )

    cooldown_seconds: int = Field(
        gt=0,
    )

    max_attempts: int = Field(
        gt=0,
    )

    length: int = Field(
        gt=0,
        lt=100,
    )

Vs Below -> Also i then listen there is:


@dataclass(frozen=True)
class OTPPolicy:
    validity_seconds: int
    cooldown_seconds: int
    max_attempts: int
    length: int

Use type Vector = list[float] for Python 3.12+ and

Vector: TypeAlias = list[float]
