### Recap { #recap }

In summary, you declare **once** the types of parameters, body, etc. as function parameters.

You do that with standard modern Python types.

You don't have to learn a new syntax, the methods or classes of a specific library, etc.

Just standard **Python**.

For example, for an `int`:

```Python
item_id: int
```

or for a more complex `Item` model:

```Python
item: Item
```

      return table.get(c);
    }

    @Override
    void setBits(BitSet bitSet) {
      bitSet.or(table);
    }
  }

  // Static constant implementation classes

  /** Implementation of {@link #any()}. */
  private static final class Any extends NamedFastMatcher {

    static final CharMatcher INSTANCE = new Any();

    private Any() {

        MockNode nodeWithMultipleClasses = new MockNode("div");
        nodeWithMultipleClasses.addAttribute("class", "container highlight active");
        assertTrue(tag.matches(nodeWithMultipleClasses));

But it was created before there existed Python type hints. So, to define every <abbr title="the definition of how data should be formed">schema</abbr> you need to use specific utils and classes provided by Marshmallow.
