Can I just use Colab or should I do both?
Thanks for reaching out.
Generally, Colab can act as a substitute for Jupyter. We consider Jupyter a better option since it is absolutely free, requires no personal information, and does not depend on your internet connection. However (without having executed the entire Python code we use in our Program in Colab myself!), I suppose that you should encounter no issues, provided that you are able to use all libraries and modules we provide throughout the Program.
Hope this helps.
