Using python in AWS Lambda, how do I put/get an item from a DynamoDB table?
In Node.js this would be something like:
dynamodb.getItem({
"Key": {"fruitName" : 'banana'},
"TableName": "fruitSalad"
}, function(err, data) {
if (err) {
context.fail('Incorrect username or password');
} else {
context.succeed('yay it works');
}
});
All I need is the python equivalent.
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
