### Don't worry about style { #dont-worry-about-style }

* Don't worry too much about things like commit message styles, I will squash and merge customizing the commit manually.

* Also don't worry about style rules, there are already automatized tools checking that.

```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 }

    // TODO(cgdecker): Add CharSource.slice?
    StringBuilder builder = new StringBuilder();
    Reader reader = concatenated.openStream(); // no need to worry about closing
    for (int i = 0; i < 8; i++) {
      builder.append((char) reader.read());
    }
    assertEquals(expected, builder.toString());
  }

      result = "running=[DONE]";
    } else if (state instanceof Blocker) {
      result = "running=[INTERRUPTED]";
    } else if (state instanceof Thread) {
      // getName is final on Thread, no need to worry about exceptions
      result = "running=[RUNNING ON " + ((Thread) state).getName() + "]";
    } else {
      result = "running=[NOT STARTED YET]";
    }
    return result + ", " + toPendingString();
  }

    // TODO(cgdecker): Add CharSource.slice?
    StringBuilder builder = new StringBuilder();
    Reader reader = concatenated.openStream(); // no need to worry about closing
    for (int i = 0; i < 8; i++) {
      builder.append((char) reader.read());
    }
    assertEquals(expected, builder.toString());
  }

Don't worry if some of these items about **containers**, Docker, or Kubernetes don't make a lot of sense yet.

* Также есть вероятность, что пулл-реквест не нужен, так как проблему можно решить **другим путём**. Тогда Вы можете предложить или спросить об этом.

### Не переживайте о стиле { #dont-worry-about-style }

* Не стоит слишком беспокоиться о таких вещах, как стиль сообщений в коммитах — при слиянии я выполню squash и настрою коммит вручную.

  that is, if they require configuration of a server process, and
  subsequent testing in-container.

  Since we're only going to concern ourselves with states where localhost is
  still active, we only need to worry about this case when the server container
  is <<not>> installed on localhost. This allows the popular pattern of starting
  a server container in-JVM, running tests against it, and shutting it down.

** SCM mojos

* `fixedquery`: has the exact value `fixedquery`.
* `$`: ends there, doesn't have any more characters after `fixedquery`.

If you feel lost with all these **"regular expression"** ideas, don't worry. They are a hard topic for many people. You can still do a lot of stuff without needing regular expressions yet.

Now you know that whenever you need them you can use them in **FastAPI**.

### No te preocupes por el estilo { #dont-worry-about-style }

* No te preocupes demasiado por cosas como los estilos de los mensajes de commit, yo haré squash y merge personalizando el commit manualmente.
