## Что используется в **FastAPI** { #used-by-fastapi }

### [Pydantic](https://docs.pydantic.dev/) { #pydantic }

Pydantic — это библиотека для определения валидации данных, сериализации и документации (с использованием JSON Schema) на основе аннотаций типов Python.

Благодаря этому он чрезвычайно интуитивен.

Например:

* [VS Code](https://code.visualstudio.com/docs/python/environments#_select-and-activate-an-environment)
* [PyCharm](https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html)

            dc_list_expiration = now + 1000 * 60 * 15; /* 15 min */

1.  If you are only changing the docstring of a class/function/method, then you
    can test it by passing that file's path to
    [tf_doctest.py](https://www.tensorflow.org/code/tensorflow/tools/docs/tf_doctest.py).
    For example:

    ```bash
    python tf_doctest.py --file=<file_path>
    ```

    This will run it using your installed version of TensorFlow. To be sure

When you run **multiple processes** of the same API program, they are commonly called **workers**.

### Worker Processes and Ports { #worker-processes-and-ports }

Remember from the docs [About HTTPS](https.md) that only one process can be listening on one combination of port and IP address in a server?

This is still true.
