Es ist so konzipiert, sehr einfach zu verwenden zu sein und es jedem Entwickler sehr leicht zu machen, andere Komponenten mit **FastAPI** zu integrieren.

## Was ist „Dependency Injection“

## Zweite Abhängigkeit, „Dependable“ und „Dependant“

Dann können Sie eine weitere Abhängigkeitsfunktion (ein „Dependable“) erstellen, die gleichzeitig eine eigene Abhängigkeit deklariert (also auch ein „Dependant“ ist):

=== "Python 3.10+"

    ```Python hl_lines="13"
    {!> ../../../docs_src/dependencies/tutorial005_an_py310.py!}
    ```

**FastAPI** has a very powerful but intuitive **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection"

	// These are keyed by the internal uid() function on collections.
	// Note this does not include `parent`, which is the *primary* dependency declared outside of transformation functions.
	collectionDependencies sets.Set[collectionUID]
	// Stores a map of I -> secondary dependencies (added via Fetch)
	objectDependencies map[Key[I]][]*dependency

	// eventHandlers is a list of event handlers registered for the collection. On any changes, each will be notified.

Explicit dependencies :: These dependencies are explicitly declared in the build script using the `dependsOn`, `mustRunAfter`, or `shouldRunAfter` methods. For example, if you want to ensure that `taskB` always runs after `taskA`, you can explicitly declare this dependency using `taskB.mustRunAfter(taskA)`.

        // packaging type.
        for (Dependency dependency : dependencies) {
            String key = dependency.getGroupId() + ":" + dependency.getArtifactId() + ":" + dependency.getVersion()
                    + (dependency.getClassifier() != null ? ":" + dependency.getClassifier() : EMPTY);
            String mKey = m.getGroupId() + ":" + m.getArtifactId() + ":" + m.getVersion();

[[implicit_dependency]]
== Implicit dependencies between tasks

This error indicates that you have a task which depends on another, but that no explicit or implicit dependency is declared between those two tasks.
As a consequence, the results of the build are dependent on the order of execution of tasks, often referred to "accidental dependencies between tasks".
