Hello! I'd recommend checking out the Pandas documention ( https://pandas.pydata.org/pandas-docs/stable/) for ideas of how to use it. Jupyter makes it possible to use interactive tools like Pandas, but it doesn't create Pandas itself so this isn't the best place to ask for support (I'd bet Pandas has a mailing list though). Another good option is the "scipy-lectures" website which has several helpful modules (and I think covers Pandas) http://scipy-lectures.org/intro/
