Which language is described as an interpreted, object-oriented, high-level programming language with dynamic semantics?

• A. Python
• B. Java
• C. C++
• D. Lisp

Answer: (A)

Think of a language that you run through an interpreter, hides low-level memory details, and builds programs from objects that interact with one another. That combination best describes Python. It is interpreted, typically executed by a Python interpreter like CPython or PyPy rather than compiled to machine code ahead of time. It is high-level, offering powerful built-in data structures and automatic memory management, so you can focus on solving problems rather than on manual resource handling. It is object-oriented, since nearly everything in Python is an object—classes define blueprints for objects, and you create instances, use methods, and employ inheritance and polymorphism. It has dynamic semantics because typing is dynamic and resolved at runtime; variables don’t have fixed types, and operations are determined by the actual objects involved, enabling flexible and rapid development.

Java and C++ share the object-oriented aspect, but they emphasize static typing and compilation, which don’t align with the “interpreted with dynamic semantics” part. Lisp is dynamic and capable of object-like patterns in its extensions, but Python lines up most directly with the described combination: interpreted, high-level, object-oriented, with dynamic typing and binding.
