### Summary Refactored the `two_sum` function to enhance clarity, improve structure, and ensure compliance with Python best practices (PEP 8). This version prioritizes intuitive logic, robust error handling, and clear documentation. ### Key Changes - **Function Renaming:** Renamed `twoSum` to `two_sum` to adhere to PEP 8 standards for function naming. - **Improved Variable Naming:** Replaced ambiguous names (`chk_map`, `compl`) with more intuitive identifiers (`seen_values`, `complement`). - **Added Type Hints:** Introduced `from typing import List, Union` to improve code clarity and provide IDE/linter support. - **Enhanced Docstring:** Expanded the docstring to include detailed function descriptions, argument explanations, and return behavior. - **Robust Return Handling:** Ensured the function explicitly returns `False` if no valid pair is found, improving clarity in edge cases. - **Improved Output Structure:** Added a `__main__` block with structured output for cleaner and more informative result display. ### Rationale These changes improve: - **Readability:** Clearer variable names and enhanced documentation make the code easier to understand for future developers (and my future self). - **Maintainability:** Improved structure provides a stronger foundation for future feature enhancements or modifications. - **Compliance:** Aligns with Python's official best practices for formatting and style (PEP 8).
