awsdynamodbparser 0.1.3

AWS DynamoDB Parser
AWS DynamoDB utility for parsing DynamoDB responses
Installation
pip install aws-dynamodb-parser

Package Contents
parse
parse is the main method exposed for parsing DynamoDB responses when using boto3.
The parse function can handle all of the data types AWS DynamoDB supports as of October 2020.
Examples
Assuming we have a table TABLE_NAME containing the following entries, with id set as the partition key and timestamp as the sort key.
All three fields included are strings.

id
timestamp
name

a77b5fc0-75cb-408c-bebf-863873506cce
2020-10-01 13:13:47.388492
First test entry

a77b5fc0-75cb-408c-bebf-863873506cce
2020-10-01 13:15:25.376589
Second test entry

2020-10-01 13:16:47.720778
Third test entry

Parsing the result from a get_item request:
import boto3
from aws_dynamodb_parser import parse

dynamodb_client = boto3.client("dynamodb")
response = dynamodb_client.get_item(
TableName="TABLE_NAME",
Key={
"id": {"S": "a77b5fc0-75cb-408c-bebf-863873506cce"},
"timestamp": {"S": "2020-10-01 13:13:47.388492"}
}
)

item = response.get("Item", {})
print(item)
# {'id': {'S': 'a77b5fc0-75cb-408c-bebf-863873506cce'}, 'timestamp': {'S': '2020-10-01 13:13:47.388492'}, 'name': {'S': 'First test entry'}}

entry = parse(item)
print(entry)
# {'id': 'a77b5fc0-75cb-408c-bebf-863873506cce', 'timestamp': '2020-10-01 13:13:47.388492', 'name': 'First test entry'}

Parsing the result from a query request:
import boto3
from aws_dynamodb_parser import parse

dynamodb_client = boto3.client("dynamodb")
response = dynamodb_client.query(
TableName="TABLE_NAME",
KeyConditionExpression="#id = :id",
ExpressionAttributeNames={
"#id": "id"
},
ExpressionAttributeValues={
":id": {"S": "a77b5fc0-75cb-408c-bebf-863873506cce"}
}
)

items = response.get("Items", [])
print(items)
# [{'id': {'S': 'a77b5fc0-75cb-408c-bebf-863873506cce'}, 'timestamp': {'S': '2020-10-01 13:13:47.388492'}, 'name': {'S': 'First test entry'}}, {'id': {'S': 'a77b5fc0-75cb-408c-bebf-863873506cce'}, 'timestamp': {'S': '2020-10-01 13:15:25.376589'}, 'name': {'S': 'Second test entry'}}]

entries = parse(items)
print(entries)
# [{'id': 'a77b5fc0-75cb-408c-bebf-863873506cce', 'timestamp': '2020-10-01 13:13:47.388492, 'name': 'First test entry'}, {'id': 'a77b5fc0-75cb-408c-bebf-863873506cce', 'timestamp': '2020-10-01 13:15:25.376589', 'name': 'Second test entry'}]
