Dict[str, Set[Tuple[int, float]]]
Type System & Annotations

Meaning

A type annotation representing a dictionary that maps string keys to sets of tuples, each tuple containing an integer and a float.

Primary Function

Specifies the exact structure of a data mapping for static type checking, enabling IDE support and preventing type errors.

Communicative Purpose

Communicates the expected shape of data where each string key associates with a collection of unique (int, float) pairs, often used for scoring, coordinates, or labeled numeric pairs.

Pattern

Dict[KeyType, Set[Tuple[IntType, FloatType]]] where KeyType=str, IntType=int, FloatType=float

Core Structure

Dict[str, Set[Tuple[int, float]]]

Função primária

Specifies the exact structure of a data mapping for static type checking, enabling IDE support and preventing type errors.

Propósito comunicativo

Communicates the expected shape of data where each string key associates with a collection of unique (int, float) pairs, often used for scoring, coordinates, or labeled numeric pairs.

Situações de gatilho

When defining function parameters, return types, or variable annotations that involve a mapping from string identifiers to sets of numeric pairs.

Contextos

Used in Python codebases with type hints, especially in data processing, machine learning, or scientific computing modules where labeled numeric pairs are grouped by string keys.

Colocados típicos

  • Dict
  • Set
  • Tuple
  • str
  • int
  • float
  • typing
  • typing.Dict
  • typing.Set
  • typing.Tuple

Substituições comuns

  • Replace str with any hashable key type (e.g.
  • int
  • Tuple)
  • replace int/float with other numeric types (e.g.
  • float
  • Decimal)
  • replace Set with List or Tuple to allow duplicates or order.

Erros comuns

Forgetting to import typing.Set, typing.Tuple, typing.Dict (for Python <3.9); using mutable default arguments like default=set(); confusing Set with List (allowing duplicates); using mutable list as set element (unhashable type); confusing int/float order in tuple.

Similar / contraste

Dict[str, List[Tuple[int, float]]] (allows duplicates, preserves order); Dict[str, Set[int]] (only integers); Dict[str, Tuple[int, float]] (single pair per key); Dict[str, Set[Tuple[float, int]]] (reversed tuple order).

Interferências

Confusing Set with List leading to duplicate entries; mistakenly assuming tuple order is irrelevant; using mutable list inside set causing unhashable type error; swapping int/float order in tuple.

Família do chunk

  • type annotations for collections
  • numeric tuples
  • mapping types

Nuance

Indicates that each key maps to a collection of unique (int, float) pairs; duplicates are automatically eliminated; order of pairs is not guaranteed.

Efeito pragmático

Signals to readers and type checkers that the data structure associates string labels with a set of numeric pairs, often used for scoring, coordinates, or labeled numeric data where uniqueness matters.
