## Use one HTTP operation per function

Don't mix HTTP operations in a single function, having one function per HTTP operation helps separate concerns and organize the code.

Do this:

```python
from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

 *
 * <p>To implement a multimap, a subclass must define the method {@link #createCollection()}, which
 * creates an empty collection of values for a key.
 *
 * <p>The multimap constructor takes a map that has a single entry for each distinct key. When you
 * insert a key-value pair with a key that isn't already in the multimap, {@code
 * AbstractMapBasedMultimap} calls {@link #createCollection()} to create the collection of values

          calling a method that are not immediately obvious from reading the
          method's implementation in isolation.
       3. You can omit Javadoc for simple classes, e.g. where they are a
          simple container for some data. However, please consider whether a
          reader might still benefit from some additional background, for
          example about why the class exists at all.

    @Test
    @DisplayName("Test NotifyResponse interface with single notification")
    void testNotifyResponseWithSingleNotification() {
        List<FileNotifyInformation> inputList = Collections.singletonList(mockNotifyInfo1);

Then we **assign those two values** of the tuple to the variables `id` and `name`.

So, if the user didn't provide an item ID, they will still receive a random suggestion.

...we do all this in a **single simple line**. 🤯 Don't you love Python? 🐍
