### Just Modern Python { #just-modern-python }

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md).

 * the well known {@link java.io.File} class. One fundamental difference
 * is the usage of a URL scheme [1] to specify the target file or
 * directory. SmbFile URLs have the following syntax:
 *
 * <blockquote><pre>
 *     smb1://[[[domain;]username[:password]@]server[:port]/[[share/[dir/]file]]][?param=value[param2=value2[...]]]
 * </pre></blockquote>
 *
 * This example:
 *
 * <blockquote><pre>

```

Então esse objeto é um "chamável".

## Classes como dependências { #classes-as-dependencies_1 }

Você deve ter percebido que para criar um instância de uma classe em Python, a mesma sintaxe é utilizada.

Por exemplo:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

* declarar o parâmetro de consulta `q` sem um `Query` nem qualquer valor padrão
* declarar o parâmetro de path `item_id` usando `Path`
* tê-los em uma ordem diferente
* não usar `Annotated`

...o Python tem uma pequena sintaxe especial para isso.

Passe `*`, como o primeiro parâmetro da função.

    }

    /**
     * Append formatted content to the buffer.
     * @see String#format(String, Object...)
     *
     * @param pattern a <a href="../util/Formatter.html#syntax">format string</a>
     * @param args arguments referenced by the format specifiers in the format string
     * @return the current builder
     */
    @Nonnull

        BASE,
        V20,
        V30,
        V31,
        V40,
        V41
    }

    /**
     * Gets the hint about the source of the problem. While the syntax of this hint is unspecified and depends on the
     * creator of the problem, the general expectation is that the hint provides sufficient information to the user to

			StorageClass{
				Parity: 4,
			},
			errors.New("Too many sections in EC:4:5"),
		},
		{
			"EC:A",
			StorageClass{
				Parity: 4,
			},
			errors.New(`strconv.Atoi: parsing "A": invalid syntax`),
		},
		{
			"AB",
			StorageClass{
				Parity: 4,
			},
			errors.New("Too few sections in AB"),
		},
	}
	for i, tt := range tests {
		gotSc, err := parseStorageClass(tt.storageClassEnv)

        }
    }

    private static List<String> filesFromMerge(String commit) throws IOException, InterruptedException, ExecutionException {
        // Git revision range syntax is part of git, not the shell; pass as-is.
        return getStdoutLines(new String[] {"git", "diff", "--name-only", commit + "^1.." + commit});
    }

something(some_argument, some_keyword_argument="foo")
```

then it is a "callable".

## Classes as dependencies { #classes-as-dependencies_1 }

You might notice that to create an instance of a Python class, you use that same syntax.

For example:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

In this case, `fluffy` is an instance of the class `Cat`.

   * use the {@code HashSet} constructor directly, taking advantage of <a
   * href="https://docs.oracle.com/javase/tutorial/java/generics/genTypeInference.html#type-inference-instantiation">"diamond"
   * syntax</a>.
   */
  @SuppressWarnings("NonApiType") // acts as a direct substitute for a constructor call
  public static <E extends @Nullable Object> HashSet<E> newHashSet() {
    return new HashSet<>();
  }
