### Check the docs

Because the available values for the *path parameter* are predefined, the interactive docs can show them nicely:

### Working with Python *enumerations*

The value of the *path parameter* will be an *enumeration member*.

#### Compare *enumeration members*

It's the most popular Python framework and is widely trusted. It is used to build systems like Instagram.

**FastAPI** doesn't make any compromise with any database, data model or tool.

It gives you all the flexibility to choose the ones that fit your project the best.

And you can use directly many well maintained and widely used packages like `passlib` and `python-jose`, because **FastAPI** doesn't require any complex mechanisms to integrate external packages.

    * Ha nem akkor látni fogunk egy tiszta hibát ezzel kapcsolatban.
* ellenőrzi hogyha van egy opcionális query paraméter `q` névvel (azaz `http://127.0.0.1:8000/items/foo?q=somequery`) `GET` kérések esetén.
    * Mivel a `q` paraméter `= None`-al van deklarálva, ezért opcionális.
    * `None` nélkül ez a mező kötelező lenne (mint például a body `PUT` kérések esetén).

- Introduce support for CEL optionals (see [CEL spec proposal 246](https://github.com/google/cel-spec/wiki/proposal-246)).
  This feature will not be fully enabled until a future Kubernetes release (likely to be v1.29), but is added in v1.28 to enable
  safe rollback on downgrade. ([#118339](https://github.com/kubernetes/kubernetes/pull/118339), [@jpbetz](https://github.com/jpbetz)) [SIG API Machinery, Auth, Cloud Provider and Testing]

 app/v1beta2 group version, because the controllers in the workloads API do not handle
 selector mutation in
 a consistent way. This restriction may be lifted in the future, but
 it is likely that that selectors will remain immutable after the move to v1.
 You can continue to use code that depends on mutable selectors by calling
 the apps/v1beta1 API in this release, but you should start planning for code

** Deployment mojos

  The concept of deployment is dependent on the availability of a some
  remote repository. Just as above, if that repository is not using
  file:// (which is highly likely to be the case), or the repository is
  not on a local filesystem, deployment will fail when offline.

** Testing mojos

  This can be a problem if the tests are more than simple unit tests;
