Which programming language is known for being interpreted, executing code line-by-line at runtime?

The correct answer is Python because it is an interpreted programming language that executes code line-by-line at runtime. This means that when a Python script is run, the Python interpreter reads the code line by line, translates it into machine code, and executes it immediately. This characteristic allows for quick testing and debugging, as developers can run parts of their code interactively and see immediate results without needing a separate compilation step.

Python’s interpreted nature contrasts with compiled languages, like C++ and Java, where the entire code typically needs to be compiled into a binary executable before it can be run. While Java does utilize an intermediate bytecode compilation step before execution on the Java Virtual Machine (JVM), making it partially interpreted, Python directly executes the source code.

JavaScript is also interpreted but primarily operates within web browsers. While it can be considered in this context, the choice of Python emphasizes its broad usage and the clarity it provides as a prominent interpreted language.
