شما پایتون استاندارد را با استفاده از تایپ ها مینویسید:

```Python
from datetime import date

from pydantic import BaseModel

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):
    return user_id


# A Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date
```

که سپس میتوان به این شکل از آن استفاده کرد:

With **FastAPI** you can take advantage of concurrency that is very common for web development (the same main attraction of NodeJS).

But you can also exploit the benefits of parallelism and multiprocessing (having multiple processes running in parallel) for **CPU bound** workloads like those in Machine Learning systems.

{* ../../docs_src/python_types/tutorial004.py hl[2] *}

## Declaring types { #declaring-types }

You just saw the main place to declare type hints. As function parameters.

This is also the main place you would use them with **FastAPI**.

### Simple types { #simple-types }

You can declare all the standard Python types, not only `str`.

You can use, for example:

        new CyclicBarrier(
            6 // for the setter threads
                + 50 // for the listeners
                + 50 // for the blocking get threads,
                + 1); // for the main thread
    ExecutorService executor = newFixedThreadPool(barrier.getParties());
    AtomicReference<AbstractFuture<String>> currentFuture = Atomics.newReference();
    AtomicInteger numSuccessfulSetCalls = new AtomicInteger();

	verify_resiliency_healing "${FUNCNAME[0]}" "${WANT}"
}

function main() {
	if [ ! -f ./mc ]; then
		wget -q https://dl.minio.io/client/mc/release/linux-amd64/mc && chmod +x ./mc
	fi

	export MC_HOST_myminio=http://minioadmin:minioadmin@localhost:9000

	cleanup_and_prune

Ось приклад стандартного Python-коду з типами:

```Python
from datetime import date
from pydantic import BaseModel

# Оголошення змінної як str
# з підтримкою автодоповнення у редакторі
def main(user_id: str):
    return user_id

# Модель Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```
