def dict_to_item(raw):
    if type(raw) is dict:

        for k,v in raw.iteritems():

                    'S': v
                }
            elif type(v) is int:
                resp[k] = {

                resp[k] = []
                for i in v:
                    resp[k].append(dict_to_item(i))
                    
        return resp
    elif type(raw) is str:
        return {
            'S': raw

from boto3.dynamodb.types import TypeSerializer
serializer = TypeSerializer()
item = {"foo": "bar"}
dyn_item = {key: serializer.serialize(value) for key, value in item.items()}

This really works for me. Thanks a lot, @yousefcodes . I was Stack on it for 1 day. Much Appreciated. Is it possible to do as this works in Update items?
