La sintaxis `{"name", "description"}` crea un `set` con esos dos valores.

Es equivalente a `set(["name", "description"])`.

#### Usar `list`s en lugar de `set`s

Si olvidas usar un `set` y usas un `list` o `tuple` en su lugar, FastAPI todavía lo convertirá a un `set` y funcionará correctamente:

  /*
   * This is an implementation of ImmutableMap optimized especially for Android, which does not like
   * objects per entry.  Instead we use an open-addressed hash table.  This design is basically
   * equivalent to RegularImmutableSet, save that instead of having a hash table containing the
   * elements directly and null for empty positions, we store indices of the keys in the hash table,

    assertFalse(actual.contains(list(3, 1)));
  }

  public void testCartesianProduct_equals() {
    Set<List<Integer>> cartesian = cartesianProduct(set(1, 2), set(3, 4));
    ImmutableSet<List<Integer>> equivalent =
        ImmutableSet.of(ImmutableList.of(1, 3), ImmutableList.of(1, 4), list(2, 3), list(2, 4));
    ImmutableSet<List<Integer>> different1 =

         * TypeVariable must have a different declaration or name. The only TypeVariable that our
         * new TypeVariable _will_ be equal to is an equivalent TypeVariable that was also created
         * by us. And that equality is guaranteed to hold because it doesn't involve the JDK
         * TypeVariable implementation at all.
         */

         * This method takes into account the ordering of known qualifiers then unknown qualifiers with lexical
         * ordering.
         * <p>
         *
         * @param qualifier
         * @return an equivalent value that can be used with lexical comparison
         */
        public static String comparableQualifier(String qualifier) {
            if (RELEASE_QUALIFIERS.contains(qualifier)) {

FastAPI é um moderno e rápido (alta performance) _framework web_ para construção de APIs com Python, baseado nos _type hints_ padrões do Python.

Os recursos chave são:

* **Rápido**: alta performance, equivalente a **NodeJS** e **Go** (graças ao Starlette e Pydantic). [Um dos frameworks mais rápidos disponíveis](#performance).
* **Rápido para codar**: Aumenta a velocidade para desenvolver recursos entre 200% a 300%. *

    return (ImmutableRangeSet<C>) EMPTY;
  }

  /**
   * Returns an immutable range set containing the specified single range. If {@link Range#isEmpty()
   * range.isEmpty()}, this is equivalent to {@link ImmutableRangeSet#of()}.
   */
  public static <C extends Comparable> ImmutableRangeSet<C> of(Range<C> range) {
    checkNotNull(range);
    if (range.isEmpty()) {
      return of();

   * formally, removes an element {@code e} such that {@code o.equals(e)}, if this queue contains
   * one or more such elements. Returns {@code true} if and only if this queue contained the
   * specified element (or equivalently, if this queue changed as a result of the call).
   *
   * @param o element to be removed from this queue, if present
   * @return {@code true} if this queue changed as a result of the call

Die Übergabe des `root_path` an `FastAPI` wäre das Äquivalent zur Übergabe der `--root-path`-Kommandozeilenoption an Uvicorn oder Hypercorn.

### Über `root_path`

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

If you come from Flask, this would be the equivalent of Flask's Blueprints.

Let's say you have a file structure like this:
