Boto3 is the Amazon Web Services (AWS) Software Development Kit (SDK) for Python, which allows developers to write software that makes use of Amazon services like S3, EC2, and DynamoDB. It provides an easy-to-use, object-oriented API as well as low-level access to AWS services.

Identifying the Symptom: ClientError
