#### Unwrapping a `dict`

If we take a `dict` like `user_dict` and pass it to a function (or class) with `**user_dict`, Python will "unwrap" it. It will pass the keys and values of the `user_dict` directly as key-value arguments.

So, continuing with the `user_dict` from above, writing:

```Python
UserInDB(**user_dict)
```

would result in something equivalent to:

```Python
UserInDB(

  }

  public void testNewIdentityHashSet() {
    Set<Integer> set = Sets.newIdentityHashSet();
    Integer value1 = new Integer(12357);
    Integer value2 = new Integer(12357);
    assertTrue(set.add(value1));
    assertFalse(set.contains(value2));
    assertTrue(set.contains(value1));
    assertTrue(set.add(value2));
    assertEquals(2, set.size());
  }

## Singular values in body

The same way there is a `Query` and `Path` to define extra data for query and path parameters, **FastAPI** provides an equivalent `Body`.

For example, extending the previous model, you could decide that you want to have another key `importance` in the same body, besides the `item` and `user`.

  private static final byte[] ARRAY234 = {(byte) 2, (byte) 3, (byte) 4};

  private static final byte[] VALUES = {Byte.MIN_VALUE, -1, 0, 1, Byte.MAX_VALUE};

  public void testHashCode() {
    for (byte value : VALUES) {
      assertThat(Bytes.hashCode(value)).isEqualTo(((Byte) value).hashCode());
    }
  }

  public void testContains() {
    assertThat(Bytes.contains(EMPTY, (byte) 1)).isFalse();
