What is true about tuples? (Select two answers.)

ATuples are immutable, which means that their contents cannot be changed during their lifetime.

BThe len { } function cannot be applied to tuples.

CAn empty tuple is written as { } .

DTuples can be indexed and sliced like lists.

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.

The len() function works on tuples, right?

I thought an empty tuple was represented by () instead of {}, so I'm pretty sure option C is wrong.

I practiced a question where we had to identify tuple properties, and I think D is correct since tuples can be indexed like lists.

I'm not sure about option B; I feel like we can use len() on tuples, but I might be mixing it up with something else.

Ah, I've got this! Tuples are immutable, you can't change their contents. And you can use the len() function on them, just like with lists. I'm feeling good about this.

I remember learning about tuples, but I'm drawing a blank on the specifics. I'll have to carefully read through the options and see which ones sound familiar.

Okay, let's think this through. Tuples are immutable, so that's definitely one of the answers. And I know they can be indexed and sliced like lists, so that's another one. Now I just need to figure out the other two.

Consistency sounds familiar, but I feel like it relates more to the state of the database rather than the transaction itself.

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.
