The correction aligns with the codebase structure where `InMemorySaver` is the primary class name in Python, while `MemorySaver` is maintained as an alias for backwards compatibility. The JavaScript/TypeScript code blocks in the same file correctly use `MemorySaver`, so no changes were needed there.\n\nThe fix addresses the documentation inconsistency reported in the GitHub issue and ensures that Python developers following the tutorial will have the correct import statement that matches the actual usage."
