redundant-literal-union (PYI051)#
Derived from the flake8-pyi linter.
What it does#
Checks for the presence of redundant Literal
types and builtin super
types in an union.
Why is this bad?#
The use of Literal
types in a union with the builtin super type of one of
its literal members is redundant, as the super type is strictly more
general than the Literal
type.
For example, Literal["A"] | str
is equivalent to str
, and
Literal[1] | int
is equivalent to int
, as str
and int
are the super
types of "A"
and 1
respectively.
