Show Suggested Answer

Suggested Answer: A

Python is an interpreted programming language, which means that the source code is translated into executable code by an interpreter at runtime, rather than by a compiler beforehand. Interpreted languages are more flexible and portable than compiled languages, but they are also slower and less efficient. Assembly and machine languages are low-level languages that are directly executed by the hardware, while compiled languages are high-level languages that are translated into machine code by a compiler before execution.

I'm going to go with A and D. Tuples are like the frozen version of lists - you can't change them, but you can still access their elements.

Haha, B is definitely wrong. The len() function works just fine with tuples! It's not like they're some kind of black box.

I'm pretty sure C is wrong. An empty tuple is written as (), not {}. That's for dictionaries.

I think A and D are correct. Tuples are like read-only lists, so you can't change them once they're created, and you can access their elements using indexes.
