==========================Inserting data to DynamoDB============================


import boto3
import random
from decimal import *


def load_transactions(dynamodb):

    table = dynamodb.Table('Movies')

    trans = {}

    trans['year'] = 2021
    trans['title'] = 'this is a great title'

    print(trans)

    table.put_item(Item=trans)


if __name__ == '__main__':


    dynamodb = boto3.resource('dynamodb',  endpoint_url = "http://localhost:8000")

    load_transactions(dynamodb)


OUTPUT:

table = dynamodb.Table('Movies')
response = table.scan()
items = response['Items']

# Prints All the Items at once
