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.

That's correct! Tuples are indeed immutable and can be accessed using indexing and slicing.

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

Yeah, tuples are pretty cool like that. You can't change them once they're created.

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.
