DynamoDB - with AWS SDK

What is wrong with this Boto3 client code snippet for DynamoDB?

import boto3
client = boto3.client('dynamodb')
response = client.get_item(TableName='Users', Key={'UserId': '123'})
print(response['Item'])

AThe Key value should be a dict with attribute type, e.g., {'UserId': {'S': '123'}}

BTableName should be lowercase 'users'

Cclient.get_item does not exist, use resource instead

Dprint statement should be print(response.Item)

Step-by-Step Solution

Solution:

Step 1: Check the Key format for client get_item
When using the low-level client, the Key must specify attribute types, e.g., {'UserId': {'S': '123'}}.
Step 2: Identify other issues
TableName is case-sensitive and usually capitalized as in the table creation. The method get_item exists on client. The print syntax is correct for a dict.
Final Answer:
The Key value should be a dict with attribute type, e.g., {'UserId': {'S': '123'}} -> Option A
Quick Check:
Client Key needs attribute type dict [OK]

Quick Trick: Client Key needs attribute type dict like {'S': 'value'} [OK]
