Ignore a specific builtin "id" using Pylint – Python

May 2, 2022

I would like to allow to redefine id as an attribute in a generic class.
Pylint catches this error as:
bam_sdk\core_element.py:7:44: W0622: Redefining built-in 'id' (redefined-builtin)
I would like to allow "id" to be overwritten, however not other builtin’s like "int, str etc.".

Is there a way to only disable this specific error for only this specific value "id"?

from typing import Optional


class Element:
    counter = 1

    def __init__(self, name: Optional[str], id: Optional[int]) -> None:
        self.id = id if id else self.__class__.counter
        self.name = name if name else f"{self.__class__.__name__}-{self.id}"
        self.__class__.counter += 1

>Solution :

It’s not the attribute it’s complaining about; it’s the parameter name. The standard convention is to append a _ to the name to avoid the shadowing.

def __init__(self, name: Optional[str], id_: Optional[int]) -> None:
    self.id = id_ if id_ else self.__class__.counter
    self.name = name if name else f"{self.__class__.__name__}-{self.id}"
    self.__class__.counter += 1

I find it slightly cleaner to modify the value of the parameter rather than using a conditional expression.

def __init__(self, name: Optional[str], id_: Optional[int]) -> None:
    if id_ is None:
        id_ = self.__class__.counter

    if name_ is None:
        name = f"{self.__class__.__name__}-{id_}"

    self.id = id_
    self.name = name
    self.__class__.counter += 1
