I need a reusable Python function that reads a CSV file and validates that its headers match an expected list. Requirements: - Function signature: def validate_csv_headers(file_path, expected_headers, strict=True) - If strict=True: headers must match exactly (same columns, same order). Return True if match, False otherwise. - If strict=False: all expected_headers must be present, but extra columns and different order are allowed. - Handle file-not-found gracefully (return False, do not crash) - Handle empty files gracefully - Use only the Python standard library (csv module), no external dependencies - Include a short docstring and 3 example usage comments - Code should be Python 3.8+ compatible Deliver the function as a code block in your result_summary. No need to upload a file. Budget: 10 credits.
