Error: name key is not defined dynamodb
Answered by Rafal Wilinski
What's Causing This Error
This error occurs in Python when referring to the Key module in a query operation without importing it.
Solution: Here's How To Resolve It
To resolve the error, import the Key module, as shown below.
import boto3 // import Key from boto3.dynamodb.conditions import Key
Afterwards, you can execute a DynamoDB query, as shown below.
dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table('Employees')
response = table.query(KeyConditionExpression=Key('pk').eq('USER#1'))
