serializers

    - helps to convert complex datatype like python_datatypes into 
        json,xml or other content types which is understandable by frontend.


    - serializers are also responsible for deserialization  which helps to
        convert parse_data back into complex data after validating
        the incomming data.


        complex data ------> python native datatype -------> json_data
                    serialization                   render in into json

    -used to render serilised data into json 


    -import jsonRenderer 

    -from restframework.renders
    
    render data into json

    json_data = JSONRenderer().render(serizer.data)
