how to put an Item in aws DynamoDb using aws Lambda with python

Using Boto3 (Latest AWS SDK for python)

You import it with

import boto3

Then call the client via

dynamodb = boto3.client('dynamodb')

Get item example

dynamodb.get_item(TableName='fruitSalad', Key={'fruitName':{'S':'Banana'}})

Put item example

dynamodb.put_item(TableName='fruitSalad', Item={'fruitName':{'S':'Banana'},'key2':{'N':'value2'}})

'S' indicates a String value, 'N' is a numeric value

For other data types refer http://boto3.readthedocs.org/en/latest/reference/services/dynamodb.html#DynamoDB.Client.put_item

Using latest AWS SDK

import boto3

def lambda_handler(event, context):
    # this will create dynamodb resource object and
    # here dynamodb is resource name
    client = boto3.resource('dynamodb')

    # this will search for dynamoDB table 
    # your table name may be different
    table = client.Table("dynamoDB")
    print(table.table_status)

    table.put_item(Item= {'id': '34','company':  'microsoft'})

If your are using AWS you can use this code sample, only you have to give permissions to this lambda function, you can find details in link
