Natural language processing project

[maaaa2401]

Hello everybody, for a project at the university I have to perform a Natural Language Processing project in python on the basis of a corpus of some Harry Potter sentences, that were evaluated in a questionnaire according to valence and arousal values.
Honestly I can't figure out a possible project that could be satisfying for me and obviously for my professor.
I already have experience in python but I am very new in the world of NLP and I am stuck because I have to use those data and can't create a project on whatever I like.
I am aware that this is quite a generic question, but if you could give me some hints, I'd be very grateful.

First install the Natural Language Toolkit: https://www.nltk.org/install.html

Then go through the tutorial here: https://www.nltk.org/

It includes ample examples and show you how you can enter your own corpus.
