I thought sorted() needed a list, not a string.

I'm a bit confused about option C; it seems like the syntax is off, but I can't recall the exact rules.

I remember practicing with the sort method, but I'm not sure if option B is valid since it's not called on a list.

Sorting and string methods, huh? I'll need to think through the correct way to use those in Python. Gotta make sure I don't overthink this and select the right options.

Ah, I see what they're getting at. This is testing our knowledge of string manipulation in Python. I'm feeling pretty confident I can identify the two valid invocations.

Okay, I think I've got this. The valid invocations are going to be the ones that follow the proper Python syntax for calling functions and methods on strings. I'll carefully evaluate each option.

Hmm, I'm a bit confused by the different ways the sorting and string methods are being used here. I'll need to double-check the correct syntax to make sure I select the right answers.

This looks like a tricky question. I'll need to carefully read through the options and think about the syntax for sorting and manipulating strings in Python.

Okay, I think I've got this. The question is asking us to add a custom status code, so I'm going to go with option B since it looks like it's creating a new Status object with the 'NO_FILES_FOUND' message.

I'm pretty sure an "idle" system is referred to as a "zombie". That's the term I'm most familiar with.

I think the answer is D - there is no charge for using the public data sets. AWS often provides certain services and resources for free, so that seems like the most logical choice here. I'll double-check the options, but I'm fairly confident in this answer.

Because 'sort' is a method that can be called on a list, and 'find' is a method that can be called on a string.

A) and B) are the way to go. But if you ask me, the real question is why we're still using Python 2 syntax in 2023. Time to upgrade, folks!

I'm surprised C) is not a valid option. It looks like a valid function call to me. Maybe the Python gods are playing tricks on us.

A) and B) are the valid options. sorted() is a built-in function that returns a new sorted list, while .sort() is a list method that modifies the list in-place.
