-# 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`.
-
-For example, you could declare that something could be a `str` or `None`:
-
-```python
-from typing import Union
-
-
-def say_hi(name: Union[str, None]):
-        print(f"Hi {name}!")
-```
-
-`typing` also has a shortcut to declare that something could be `None`, with `Optional`.
-
-Here's a tip from my very **subjective** point of view:
-
-* 🚨 Avoid using `Optional[SomeType]`
-* Instead ✨ **use `Union[SomeType, None]`** ✨.
-
-Both are equivalent and underneath they are the same, but I would recommend `Union` instead of `Optional` because the word "**optional**" would seem to imply that the value is optional, and it actually means "it can be `None`", even if it's not optional and is still required.
-
-I think `Union[SomeType, None]` is more explicit about what it means.
-
-It's just about the words and names. But those words can affect how you and your teammates think about the code.
-
-As an example, let's take this function:
-
-```python
-from typing import Optional
-
-
-def say_hi(name: Optional[str]):
-    print(f"Hey {name}!")
-```
-
-The parameter `name` is defined as `Optional[str]`, but it is **not optional**, you cannot call the function without the parameter:
-
-```Python
-say_hi()  # Oh, no, this throws an error! 😱
-```
-
-The `name` parameter is **still required** (not *optional*) because it doesn't have a default value. Still, `name` accepts `None` as the value:
-
-```Python
-say_hi(name=None)  # This works, None is valid 🎉
-```
-
-The good news is, in most cases, you will be able to simply use `|` to define unions of types:
-
-```python

 Help with translations is VERY MUCH appreciated! And it can't be done without the help from the community. 🌎 🚀
 
+Here are the steps to help with translations.
+
+#### Translation PRs
+
 Translation pull requests are made by LLMs guided with prompts designed by the FastAPI team together with the community of native speakers for each supported language.
 
-#### LLM Prompt per Language
+These translations are normally still reviewed by native speakers, and here's where you can help!
 
-Each language has a directory: <a href="https://github.com/fastapi/fastapi/tree/master/docs" class="external-link" target="_blank">https://github.com/fastapi/fastapi/tree/master/docs</a>, in it you can see a file `llm-prompt.md` with the prompt specific for that language.
+* Check the currently <a href="https://github.com/fastapi/fastapi/pulls" class="external-link" target="_blank">existing pull requests</a> for your language. You can filter the pull requests by the ones with the label for your language. For example, for Spanish, the label is <a href="https://github.com/fastapi/fastapi/pulls?q=is%3Aopen+sort%3Aupdated-desc+label%3Alang-es+label%3Aawaiting-review" class="external-link" target="_blank">`lang-es`</a>.
 
-For example, for Spanish, the prompt is at: <a href="https://github.com/fastapi/fastapi/blob/master/docs/es/llm-prompt.md" class="external-link" target="_blank">`docs/es/llm-prompt.md`</a>.
+* When reviewing a pull request, it's better not to suggest changes in the same pull request, because it is LLM generated, and it won't be possible to make sure that small individual changes are replicated in other similar sections, or that they are preserved when translating the same content again.
 
-If you see mistakes in your language, you can make suggestions to the prompt in that file for your language, and request the specific pages you would like to re-generate after the changes.

+#### Using `Union` or `Optional` { #using-union-or-optional }
+
+If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view:
+
+* 🚨 Avoid using `Optional[SomeType]`
+* Instead ✨ **use `Union[SomeType, None]`** ✨.
+
+Both are equivalent and underneath they are the same, but I would recommend `Union` instead of `Optional` because the word "**optional**" would seem to imply that the value is optional, and it actually means "it can be `None`", even if it's not optional and is still required.
+
+I think `Union[SomeType, None]` is more explicit about what it means.
+
+It's just about the words and names. But those words can affect how you and your teammates think about the code.
+
+As an example, let's take this function:
+
+{* ../../docs_src/python_types/tutorial009c_py39.py hl[1,4] *}
+
+The parameter `name` is defined as `Optional[str]`, but it is **not optional**, you cannot call the function without the parameter:
+
+```Python
+say_hi()  # Oh, no, this throws an error! 😱
+```
+
+The `name` parameter is **still required** (not *optional*) because it doesn't have a default value. Still, `name` accepts `None` as the value:
+
+```Python
+say_hi(name=None)  # This works, None is valid 🎉
+```
+
+The good news is, once you are on Python 3.10 you won't have to worry about that, as you will be able to simply use `|` to define unions of types:
+
+{* ../../docs_src/python_types/tutorial009c_py310.py hl[1,4] *}
+
+And then you won't have to worry about names like `Optional` and `Union`. 😎
+
+#### Generic types { #generic-types }
+
+These types that take type parameters in square brackets are called **Generic types** or **Generics**, for example:

+Python also has a feature that allows putting **additional <abbr title="Data about the data, in this case, information about the type, e.g. a description.">metadata</abbr>** in these type hints using `Annotated`.
 
-You can import `Annotated` from `typing`.
+Since Python 3.9, `Annotated` is a part of the standard library, so you can import it from `typing`.

 Python itself doesn't do anything with this `Annotated`. And for editors and other tools, the type is still `str`.

-    * **Starlette** : (utilise Uvicorn) un microframework web

-    * On n'écrit pas une application directement avec Uvicorn. Cela signifie que le code devrait inclure, au minimum, plus ou moins tout le code offert par Starlette (ou **FastAPI**). Et si on fait cela, l'application finale aura la même surcharge que si on avait utilisé un framework, tout en minimisant la quantité de code et les bugs.

-    * FastAPI apporte des fonctionnalités supplémentaires à Starlette. Des fonctionnalités dont vous avez presque toujours besoin lors de la création d'une API, comme la validation des données et la sérialisation. En l'utilisant, vous obtenez une documentation automatique « gratuitement » (la documentation automatique n'ajoute même pas de surcharge à l’exécution, elle est générée au démarrage).
-    * Si on n'utilisait pas FastAPI mais directement Starlette (ou un autre outil comme Sanic, Flask, Responder, etc.), il faudrait implémenter toute la validation des données et la sérialisation soi‑même. L'application finale aurait donc la même surcharge que si elle avait été construite avec FastAPI. Et dans de nombreux cas, cette validation des données et cette sérialisation représentent la plus grande quantité de code écrite dans les applications.
-    * De ce fait, en utilisant FastAPI on minimise le temps de développement, les bugs, le nombre de lignes de code, et on obtient probablement les mêmes performances (voire de meilleures performances) que l'on aurait pu avoir sans ce framework (car il aurait fallu tout implémenter dans votre code).
-    * Si on compare FastAPI, il faut le comparer à d'autres frameworks d’application web (ou ensembles d'outils) qui fournissent la validation des données, la sérialisation et la documentation, comme Flask-apispec, NestJS, Molten, etc. Des frameworks avec validation des données, sérialisation et documentation automatiques intégrées.
