Hello Readers! In this blog we will see how to upload data on AWS DynamoDB using Boto3 in a few easy steps. So, let’s not waste any time.

We have some following prerequisites for starting it:

  1. You must have installed Python3 on your system.
  2. You must have installed Boto3 on your system. Do prefer this blog for the setup of Boto3:
  3. Install AWS CLI and Configure it. If you want to check if you have configured it or not, you can check it like this.
aws configure

Make sure to complete all the above steps before starting.

Let’s get started!

Our first step is to create a DynamoDB. We will create it by using AWS Console. So, follow the following steps for creating a DynamoDB in AWS:


Click on Create Table.


Fill here the table details. Give here the name of the table as per your wish. You have to give a primary key which we all know is a unique key. It should be different for every person at the table. So, here I will specify emp_id as a primary key.

After filling the fields. Click on Create. And you can see here AWS is creating a table for us in DynamoDB.


After sometime you can see here the status of the table is active.


So, first let’s add data manually in the DynamoDB table.

For this open your table and move to Create item.

create item

Select here the type of item you want to add. Here I am adding string item.


Fill here the attribute name and value you want to add. And Click on Create Item.


It is created now as we can see here.

Let’s upload data by using boto3:

We will do it through a boto3 program. In this program I am creating boto3 objects. I am specifying the name of the DynamoDB table (3rd line) in which we want to insert data.

I will use the put_item method here in my program. It is basically used to create a new item and replaces an old item with a new item in the DynamoDB table.

import boto3

db = boto3.resource('dynamodb')
table = db.Table("employees")


So, let’s run the code and see the result.


It’s done. Now lets see:

How to get data from the DynamoDB table using boto3:

For this we have to use the get_item method. And in response we will get all the values matching with emp_id : 2.

import boto3

db = boto3.resource('dynamodb')
table = db.Table("employees")

response = table.get_item(

let’s run the code and see the result. We are getting here all the data of employee whose emp_id is 2.

Congrats! 👏 We are successfully done now!
