The 20% of NumPy that you need to know to get 80% of the value.
NumPy is a numeric computation library that is the foundation of many other Python data science libraries. Using pandas? It's built on NumPy. Using Scikit-Learn? Also built on NumPy.
If you're going to be doing data science in Python, you're going to need to know how to use the primary object in NumPy-NumPy arrays.
But, there are really only a handful of things you need to know to get up and running quickly in NumPy, and that's what we're going to cover in this video.

If you need to get your professional data science environment set up, here's a guide on exactly how to do that: www.projectdatascience.com/step-by-step-guide-to-setting-up-a-professional-data-science-environment-on-a-mac/ (Or you can watch this video: ua-cam.com/video/cn7CnFIQUBo/v-deo.html)
If you prefer a blog version of this NumPy tutorial, you can find that here: www.projectdatascience.com/80-20-numpy/
And finally, here's a course that walks you through a whole machine learning / data science project from start to finish in Python: courses.projectdatascience.com/bundles/introduction-to-practical-data-science-in-python

  • @paulspray8363

    hmmmm, I ended up tracing back to check for where I went wrong in the last part but I think I got there. Eventually corrected what was returning test set accuracy as 100% to more like 97%. I think i misused the parameters to model.fit the first try because I had made comparative versions of the fit before the cross validation and tuning. Great videos will definitely do a re-walk through to check I had things right.

    i found the tutorial strait to the point. I struggled a lot trying to get a dark theme for my jupyter notebook which came with a lot issues and didn't eventually work. Your tutorial ultimately brought the breakthrough I needed.

    Hi Mate: I am currently in an apprenticeship for data science work in IT and I hope this helps me understand the topic a little better. I am curious though, is there any technical reason for working in a jupyter notebook as opposed to a bunch of .py files? Or is it easier for educational purposes?

  • @thesosasoundproductions5033

    Hey bud, thanks for the video it's great. I have a question about my Jupyter notebook. When I start coding, I see your notebook changes colors. like for example when you type import its green and when you type print its red. Mine always stays white. what am I doing wrong? I have downloaded the latest version, but it doesn't change colors at all. Also, I see you notebook is white. Mine comes automatically in black. Could this be why? I just want to see the changes, so I don't get confused. Could you give me a suggestion on what to do? Thank you in advance
