/// tip | Tipp

Wenn Sie in Ihrem Editor strikte Typchecks haben, mypy, usw., können Sie den Funktions-Rückgabetyp als <abbr title='„Irgend etwas“'>`Any`</abbr> deklarieren.

/// tip | Tipp

Einige Editoren prüfen, ob Funktionsparameter nicht verwendet werden, und zeigen das als Fehler an.

Wenn Sie `dependencies` im *Pfadoperation-Dekorator* verwenden, stellen Sie sicher, dass sie ausgeführt werden, während gleichzeitig Ihr Editor/Ihre Tools keine Fehlermeldungen ausgeben.

    set("k1", "a", "a")

    // Create an editor for k1. Detach it by clearing the cache.
    val editor = cache.edit("k1")!!
    editor.setString(0, "bb")
    editor.setString(1, "bb")
    cache.evictAll()

    // Create a new value in its place.
    set("k1", "ccc", "ccc")
    assertThat(cache.size()).isEqualTo(6)

///

By doing that, your editor can provide support even while processing items from the list:

<img src="/img/python-types/image05.png">

Without types, that's almost impossible to achieve.

Notice that the variable `item` is one of the elements in the list `items`.

And still, the editor knows it is a `str`, and provides support for that.

/// tip

Some editors check for unused function parameters, and show them as errors.

Using these `dependencies` in the *path operation decorator* you can make sure they are executed while avoiding editor/tooling errors.

### Editor support { #editor-support }

All the framework was designed to be easy and intuitive to use, all the decisions were tested on multiple editors even before starting development, to ensure the best development experience.

So kann ihr Editor Sie unterstützen:

* in <a href="https://code.visualstudio.com/" class="external-link" target="_blank">Visual Studio Code</a>:

![Editor Unterstützung](https://fastapi.tiangolo.com/img/vscode-completion.png)

* in <a href="https://www.jetbrains.com/pycharm/" class="external-link" target="_blank">PyCharm</a>:

  internal fun completeEdit(
    editor: Editor,
    success: Boolean,
  ) {
    val entry = editor.entry
    check(entry.currentEditor == editor)

    // If this edit is creating the entry for the first time, every index must have a value.
    if (success && !entry.readable) {
      for (i in 0 until valueCount) {
        if (!editor.written!![i]) {
          editor.abort()

///

Door dat te doen, kan je editor ondersteuning bieden, zelfs tijdens het verwerken van items uit de list:

<img src="/img/python-types/image05.png">

Zonder types is dat bijna onmogelijk om te bereiken.

Merk op dat de variabele `item` een van de elementen is in de lijst `items`.

Toch weet de editor dat het een `str` is, en biedt daar vervolgens ondersteuning voor aan.

Dokümantasyona tekrardan çok nadir olarak geleceksin.
