I passed the challenge “Mean-Variance-Standard Deviation Calculator,” but my answer seems so very clunky to me, and it almost feels like I’m missing something or doing something wrong.

Anyone willing to give my answer some constructive feedback?

My head is still spinning from all the tutorial videos. Starting to learn Python, Jupyter, Numpy, Pandas, and Matplotlib all around the same time is more than my little brain can handle.

Thanks!
