```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```

and then we call:

```Python
user_dict = user_in.dict()
```

we now have a `dict` with the data in the variable `user_dict` (it's a `dict` instead of a Pydantic model object).

And if we call:

```Python
print(user_dict)
```

we would get a Python `dict` with:

```Python
{
    'username': 'john',

	err = obj.MakeBucket(b.Context(), bucket, MakeBucketOptions{})
	if err != nil {
		b.Fatal(err)
	}

	objSize := 128 * humanize.MiByte

	// PutObjectPart returns etag of the object inserted.
	// etag variable is assigned with that value.
	var etag string
	// get text data generated for number of bytes equal to object size.
	textData := generateBytesData(objSize)
	// generate md5sum for the generated data.

# Declare a variable as a str

Imagine que você queira que um parâmetro tenha o nome `item-query`.

Desta maneira:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Mas o nome `item-query` não é um nome de váriavel válido no Python.

O que mais se aproxima é `item_query`.

Mas ainda você precisa que o nome seja exatamente `item-query`...
