```

...this would work:

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}
```

And of course, you can define some parameters as required, some as having a default value, and some entirely optional:

=== "Python 3.10+"

    ```Python hl_lines="8"
    {!> ../../../docs_src/query_params/tutorial006_py310.py!}
    ```

=== "Python 3.8+"

The same way, you can define logic (code) that should be executed when the application is **shutting down**. In this case, this code will be executed **once**, **after** having handled possibly **many requests**.

   * @since 12.0 (present as {@code compare} since 2.0)
   */
  public abstract ComparisonChain compareFalseFirst(boolean left, boolean right);

  /**
   * Ends this comparison chain and returns its result: a value having the same sign as the first
   * nonzero comparison result in the chain, or zero if every result was zero.
   */
  public abstract int result();

#         * functions;
#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
#         * compound commands having a testable exit status, especially «case»;
#         * various built-in commands including «command», «set», and «ulimit».

    These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.
