Resolved: Error on Final Course Exam
Thanks for your hard work on this course. I really appreciate it. I think there is an error, or a slight miscommunication, on the final exam. On the question here, you reference location-based indexing, which you stated in another part of the course was related to explicit indexing. But in this context, you changed the meaning to be implicit based integer position indexing. I think that you should either change the reference in the course exam or change the answer to the question. Let me know what you think.
Check out #3 on this slide from the course. Thanks for your consideration.
Thanks for reaching out.
In this question, location-based indexing refers to accessing data by its position within the Series, which pandas supports through zero-based integer indexing. Even when labels are present, a Series still maintains an implicit positional order, allowing access via an integer index. Therefore, using
start_date_deposits[3] correctly retrieves the value 4500.Hope this helps.
Best,

Hey Tsvetelin,
thanks for the answer, i appreciate the time you took to answer it. But i must push back on this a bit. Please notice the distinction made in comment #3 from the course, which i linked above. There is a specific difference made between the terms location and position in the course.
Location = explicit label based
Position = implicit position based
the course defines these terms clearly as 2 different things. Therefore, on the exam you cannot use them interchangeably because in the course they are defined and 2 separate techniques. This ambiguity in terminology makes the question ambiguous at best.
let me know what you think after reviewing the course material and definitions outlined there. Thank you!

Hi Justin and Tsvetelin!
I hope you don't mind if I join the conversation.
@Justin: Thank you very much for the kind words, also for spotting this error!
Please excuse us for the confusion, of course this quetstion is asking for position-based indexing! I corrected it and just uploaded it, you should be able to see the corrected version now.
Hope this helps!
Kind regards,
Martin
