DynamoDB - with AWS SDK

Identify the error in this retry logic snippet for DynamoDB in Python:

try:
    response = client.get_item(TableName='MyTable', Key={'id': {'S': '123'}})
except ClientError as e:
    if e.response['Error']['Code'] == 'ThrottlingException':
        client.get_item(TableName='MyTable', Key={'id': {'S': '123'}})
    else:
        raise e

ANo error, code retries correctly

BShould not raise exception in else block

CError code check is incorrect

DRetry call is not inside a try-except block

Step-by-Step Solution

Solution:

Step 1: Analyze retry call placement
The retry call is made without a try-except block, so if it fails again, it will raise an unhandled exception.
Step 2: Understand proper retry handling
Retries should be wrapped in try-except to handle repeated failures gracefully.
Final Answer:
Retry call is not inside a try-except block -> Option D
Quick Check:
Retry without try-except risks unhandled errors [OK]

Quick Trick: Always wrap retries in try-except to catch repeated errors [OK]

Common Mistakes:

MISTAKES

Not wrapping retry calls in error handling
