## 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();

        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();

    //                                                                      Search Execute
    //                                                                      ==============
    /**
     * Displays the main path mapping administration page.
     *
     * @param form the search form containing search criteria
     * @return HTML response for the path mapping list page
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })

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
```

Приклад використання цієї моделі:

```Python

 * {@link org.codelibs.fess.crawler.exception.CrawlerSystemException} in case of errors.
 * </p>
 *
 * <p>
 * The {@link #storeData(ResponseData, ResultData)} method is the main entry point for storing
 * the content of a crawled resource. The {@link #getData(AccessResultData)} method retrieves
 * the stored file path as a File object.
 * </p>
 */
public class FileTransformer extends HtmlTransformer {

    // need a long enough string for the buffer to hit 0 remaining before the copy completes
    String string = Strings.repeat("0123456789", 100);
    StringBuilder b = new StringBuilder();
    // the main assertion of this test is here... the copy will fail if the buffer size goes down
    // each time it is not filled completely
    long copied = CharStreams.copy(newNonBufferFillingReader(new StringReader(string)), b);

    private BelowAll() {
      /*
       * No code ever sees this bogus value for `endpoint`: This class overrides both methods that
       * use the `endpoint` field, compareTo() and endpoint(). Additionally, the main implementation
       * of Cut.compareTo checks for belowAll before reading accessing `endpoint` on another Cut
       * instance.
       */
      super("");
    }

    @Override

    // need a long enough string for the buffer to hit 0 remaining before the copy completes
    String string = Strings.repeat("0123456789", 100);
    StringBuilder b = new StringBuilder();
    // the main assertion of this test is here... the copy will fail if the buffer size goes down
