# Advanced Python Types { #advanced-python-types }

Here are some additional ideas that might be useful when working with Python types.

## Using `Union` or `Optional` { #using-union-or-optional }

If your code for some reason can't use `|`, for example if it's not in a type annotation but in something like `response_model=`, instead of using the vertical bar (`|`) you can use `Union` from `typing`.

	// fixLongPath, but short enough not to make a path component
	// longer than 255, which is illegal on Windows. (which
	// doesn't really matter anyway, since this is purely a string
	// function we're testing, and it's not actually being used to
	// do a system call)
	veryLong := "l" + strings.Repeat("o", 248) + "ng"
	for _, test := range []struct{ in, want string }{
		// Short; unchanged:

        // there are bugs in various JVM that have problems doing this across
        // different filesystem. So we'll incur the small hit to actually copy
        // here and be safe. jvz.
        // ----------------------------------------------------------------------------

        try {
            Files.createDirectories(destination.toPath().getParent());

Make sure you evaluate if the **benefits** for your use case compensate the **drawbacks**. 🤓

## GraphQL Libraries { #graphql-libraries }

Here are some of the **GraphQL** libraries that have **ASGI** support. You could use them with **FastAPI**:

* [Strawberry](https://strawberry.rocks/) 🍓
    * With [docs for FastAPI](https://strawberry.rocks/docs/integrations/fastapi)

### `Union` in Python 3.10 { #union-in-python-3-10 }

In diesem Beispiel übergeben wir `Union[PlaneItem, CarItem]` als Wert des Arguments `response_model`.

Da wir es als **Wert an ein Argument übergeben**, anstatt es in einer **Typannotation** zu verwenden, müssen wir `Union` verwenden, sogar in Python 3.10.

Wäre es eine Typannotation gewesen, hätten wir den vertikalen Strich verwenden können, wie in:

```Python

  "http://localhost:8080/auth/admin/realms/{realm}/users/{userid}"
```

### Configure MinIO

```
export MINIO_ROOT_USER=minio
export MINIO_ROOT_PASSWORD=minio123
minio server /mnt/export
```

Here are all the available options to configure OpenID connect

```
mc admin config set myminio/ identity_openid

KEY:
identity_openid  enable OpenID SSO support

ARGS:

                verifyPropertyValue(propertyKey, filteredValue); // null checked
                return filterPropertyAsDefault(filteredValue); // not null here
            }

            private String getFromCache(final String propertyKey) {
                try {
                    return cache.get(propertyKey, () -> {

        * A key `schema`, that has as the value the JSON Schema from the model, here's the correct place.
            * **FastAPI** adds a reference here to the global JSON Schemas in another place in your OpenAPI instead of including it directly. This way, other applications and clients can use those JSON Schemas directly, provide better code generation tools, etc.
