FastAPI will use this `response_model` to do all the data documentation, validation, etc. and also to **convert and filter the output data** to its type declaration.

/// tip

If you have strict type checks in your editor, mypy, etc, you can declare the function return type as `Any`.

import org.jspecify.annotations.NullUnmarked;

/** Benchmarks for the hashing of UTF-8 strings. */
@NullUnmarked
public class HashStringBenchmark {
  static class MaxCodePoint {
    final int value;

    /**
     * Convert the input string to a code point. Accepts regular decimal numerals, hex strings, and
     * some symbolic names meaningful to humans.
     */
    private static int decode(String userFriendly) {
      try {

Because the editor knows the types of the variables, you don't only get completion, you also get error checks:

<img src="/img/python-types/image04.png">

Now you know that you have to fix it, convert `age` to a string with `str(age)`:

{* ../../docs_src/python_types/tutorial004.py hl[2] *}

## Declaring types { #declaring-types }

You just saw the main place to declare type hints. As function parameters.

     *
     * @return the parent map

    public Map<K, V> getParent() {
        return parent;
    }

    /**
     * Converts a key to camelCase.
     *
     * @param key the key to convert
     * @return the converted key
     */
    protected Object toCamelCase(final Object key) {
        if (key == null) {
            return key;
        }
        String keyStr = key.toString();

        "price": 42.0,
        "tax": 3.2
    },
    "user": {
        "username": "dave",
        "full_name": "Dave Grohl"
    },
    "importance": 5
}
```

Again, it will convert the data types, validate, document, etc.

## Multiple body params and query { #multiple-body-params-and-query }

Of course, you can also declare additional query parameters whenever you need, additional to any body parameters.
