New learner in Python, and need help on the term explanation

[BaicaiPy]

• Auto load the initial data given in pdf file
• You required to use an appropriate data structure to represent the initial data in-memory.
• It is not necessary to save the data to a file.

Need help on the first two points, and wondering why 'r', 'w', can't read the file

What is the meaning of the second point? do I need to create anything?

need to see what the data in PDF looks like, but the second statement hints at figuring out the appropriate data structure to use for representing the data in python, list, dictionary, etc. and to then populate that structure.

but it gives me a empty list.
