Here, `new_dict` will contain all the key-value pairs from `old_dict` plus the new key-value pair:

```Python
{
    "old key": "old value",
    "second old key": "second old value",
    "new key": "new value",
}
```

When you declare other function parameters that are not part of the path parameters, they are automatically interpreted as "query" parameters.

{* ../../docs_src/query_params/tutorial001_py39.py hl[9] *}

The query is the set of key-value pairs that go after the `?` in a URL, separated by `&` characters.

For example, in the URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...the query parameters are:

* `skip`: with a value of `0`

    // safeMin <= {hi,lo} <= safeMax
    // where {hi,lo} are characters forming a surrogate pair such that:
    // codePointOf(hi, lo) > safeMax
    // which would result in the surrogate pair being (wrongly) considered safe.
    // If we clip the safe range used during the per-character tests so it is
    // below the values of characters in surrogate pairs, this cannot occur.
    // This approach does mean that we break out of the fast path code in cases

        // Check encoded name (TEST -> encoded as pairs)
        // T = 0x54 -> upper nibble: 0x5 -> 0x46 (F), lower nibble: 0x4 -> 0x45 (E)
        assertEquals('F', dst[1]); // (0x54 >> 4) + 0x41 = 0x46 = 'F'
        assertEquals('E', dst[2]); // (0x54 & 0x0F) + 0x41 = 0x45 = 'E'

        // Check padding (positions 8-30 should be 'CA' pairs for spaces)
        for (int i = 8; i < 31; i += 2) {
