Understanding Python dunder methods and naming conventions

This is a foundational Python language-knowledge question that tests whether you understand Python's special-method naming convention and the terminology used in the Python community. It is particularly useful for candidates preparing for roles that involve writing production Python code, such as quantitative research or backend development.

The question probes your familiarity with how Python implements operator overloading, object lifecycle management, and class customization. Understanding this convention is essential when reading or writing Python libraries, debugging unexpected behaviour, and communicating clearly with other Python developers about language features.
