Meaning
Type annotation indicating a set containing floating-point numbers.
Primary Function
Specifies that a variable, parameter, or return value should be a set of floats for static type checking.
Communicative Purpose
Communicates the expected element type of a set to type checkers and human readers.
Pattern
Set[<type>]
Core Structure
Set[float]
Função primária
Specifies that a variable, parameter, or return value should be a set of floats for static type checking.
Propósito comunicativo
Communicates the expected element type of a set to type checkers and human readers.
Situações de gatilho
When annotating variables, function parameters, or return values that should hold a set of floats, especially when using static type checkers like mypy.
Contextos
In Python code with type hints, such as function signatures, variable assignments, return annotations, and variable annotations.

Substituições comuns
- Set[int]
- Set[str]
- Set[Any]
- Set[float] | None
Erros comuns
Using built-in set instead of typing.Set; forgetting to import Set from typing; using lowercase set; confusing with frozenset.
Similar / contraste
List[float], Tuple[float, ...], Set[int], Dict[str, float]
Interferências
Confusing mutable Set with immutable frozenset; mixing up Set[float] with Sequence[float].
Família do chunk
- Set[int]
- Set[str]
- Set[object]
- List[float]
- Dict[str
- float]
Nuance
Denotes a mutable set; use frozenset[float] for an immutable variant.
Efeito pragmático
Signals to static type checkers and readers that the collection holds floats and is mutable.
Dica de memória
Imagine a basket that only holds floating‑point numbers.
