Thanujaroyal24/Slash-Mark-basictask1-SentimentAnalysis- ? reverse-engineered prompt

Build me a simple sentiment analysis notebook that takes a bunch of text reviews or comments and tells me if each one is positive, negative, or neutral.

I want it to be easy to run in Jupyter, with clear steps for loading the data, cleaning the text, training a basic model, and testing it on a few example sentences. Please include a small sample dataset or use a common public one if needed, and show the results in a way that is easy to understand, like accuracy and a few sample predictions.

If you need to look up current best practice or a good public dataset, go ahead and do that. Keep it straightforward and beginner friendly so I can follow along and reuse it for my own text data.
