Excellent first project, Hang! This project is green. 🟢
You implemented most functions according to the specification and had good code style throughout. Great use of helper functions and parsing nested data structures. Nice job finishing out the tests as well. I would recommend making more frequent commits as you progress through the milestones.
Yes, list comprehensions definitely can condense the number of lines of code, though they effectively do the same as a for loop-conditional-append structure. For some of the "get unique ..." functions, a set data type could've been used because of its helpful property of containing all unique values. It can be easily converted to a list to meet the function's return type expectation. I think your implementations were good as they are!
See my line-by-line comments for more detail. Keep up the great work!

👍🏻 Great assert statements! Love that you used all the constants provided. Makes it a very thorough test.

Would advise to omit or comment out print statements in your final submission! In large projects, the console is great for debugging but when it's used in production or by other developers who are unfamiliar with your code, an excess of printing can clutter and confuse them as they look at the console raising questions like “What does this mean, why is it printed, where is this coming from?”

👍🏻 Great assert statements! Love that you used all the constants provided by testing the whole dictionary value. Makes it a very thorough test.

Great logic and parsing through this nested data structure.

Interesting application of enumerate! Would recommend variable names that are more descriptive so one would more easily know what is represented by i and n.

Yes! This helper function is very handy here.

Again, great use of a helper function!

This project was challenging, but I learned a lot through trial and error. Aside from list comprehensions, what other ways can I condense my code or make it more readable. Were there any methods I could have used instead? Should I include more comments about what some of lines are doing, and should I exclude some of my pseudocode type comments.
