* Even dependencies can have dependencies, creating a hierarchy or **"graph" of dependencies**.
* All **automatically handled** by the framework.
* All the dependencies can require data from requests and **augment the path operation** constraints and automatic documentation.

* Dependencylerin bile dependencies'i olabiliyor, FastAPI bunun  için **graph of "dependency"** yaratıyor.
* Hepsi **otomatik olarak** FastAPI tarafından hallediliyor.

You are free to use each operation (HTTP method) as you wish.

**FastAPI** doesn't enforce any specific meaning.

The information here is presented as a guideline, not a requirement.

For example, when using GraphQL you normally perform all the actions using only `POST` operations.

### Step 4: define the **path operation function**

This is our "**path operation function**":

* **path**: is `/`.

## Pydantic 特性

   * Finalizer directly with no problems.
   *
   * If this library is loaded in an application class loader, it's important that Finalizer not
   * have a strong reference back to the class loader. Otherwise, you could have a graph like this:
   *
   * Finalizer Thread runs instance of -> Finalizer.class loaded by -> Application class loader
   * which loaded -> ReferenceMap.class which has a static -> FinalizableReferenceQueue instance
   *
