What is the purpose of return statement with (**)

Question

I am reading about Django serialization

class SnippetSerializer(serializers.Serializer):
    id = serializers.IntegerField(read_only=True)
    title = serializers.CharField(required=False, allow_blank=True, max_length=100)
    code = serializers.CharField(style={'base_template': 'textarea.html'})
    linenos = serializers.BooleanField(required=False)
    language = serializers.ChoiceField(choices=LANGUAGE_CHOICES, default='python')
    style = serializers.ChoiceField(choices=STYLE_CHOICES, default='friendly')

    def create(self, validated_data):
        """
        Create and return a new `Snippet` instance, given the validated data.
        """
        return Snippet.objects.create(**validated_data)

Why do we need ** in return statement?

This has nothing to do with return, this is passing the validated_data dict to the `create()` method as keyword args. — Daniel Roseman, May 15 '18 at 08:02
It is not in return statement but in function call statement. — Sraw, May 15 '18 at 08:02
you need to understand *args and **kwargs in python (Read: https://learnbatta.com/blog/how-to-use-args-and-kwargs-in-python-3/) — anjaneyulubatta505, May 15 '18 at 08:22

When you want to use keyword parameter as an argument you need to specify using **
