Botocore is the low-level library that powers boto3, providing the core functionality for interacting with AWS services through Python. It handles the underlying details like request signing, response parsing, and API communication, making it useful when you need fine-grained control over AWS API calls or want to build custom AWS tools. Most developers use boto3 instead, but botocore is available if you need to work directly with AWS service operations or build your own higher-level abstractions.
