Pandas VS NumPy

If you really want to store it all (labels included) in one data structure, you should look up pandas.

Another question you may be asking is: "What about skill players?" Well, what about them? Skill players are defined as players that consistently tote the rock. I was able to filter out skill player's performance in different combine events using pandas. For our purposes, the following positions (as listed on PRF) were considered 'skill players': WR, RB, QB, TE, DB, LB. In included linebackers but if you want to not include them, knock yourself out. It kind of only helps my case that the likes of Roquan Smith and Nakobe Dean don't count for the SEC. When only considering skill players, the SEC ranks 2nd to the Big 12 in 40-yard dash times. In the other combine events for which there is data, the SEC ranks first in none of them.

You glossed over the fact that `.pct_change` isn't actually "percent change" as documented. More fun reading: https://github.com/pandas-dev/pandas/issues/20752

I suggest pandas might be a great tool for you as you will be able to read write excel / csv files and process them and see how you get on.

Now to implement this one, we'll have to do some manipulation to our account values. Let's use the power of numpy to help us out here (oh and it's also the same in pandas too. We'll be using np.diff to take the returns of our account values and resampling them.

Increase code efficiency: Python is designed for ease of use and easy extension, but not performance. As a developer, the onus is on you to do more work so that the application executes less code. Whenever possible use vectorized library functions instead of loops. Python is successful in data science because of the pre-compiled code offered by data-appropriate libraries in the pydata stack such as pandas and numpy.

Built on top of Python, pandas is an open source data analysis and manipulation tool, similar to NumPy. While it relies on NumPy arrays for much of its manipulation and computation, pandas makes it easier to visualize and explore data, helping our team make better sense of the large amounts of data we work with on a daily basis.

Dataframes are not meant to be as flexible as lists in terms of extending the data they hold, dataframes are much more "deliberate". Ideally if you're trying to dynamically add data to a dataframe you should first collect all the data and then initialize the dataframe once. Or collect separate dataframes and concat them once. The pandas developers are even thinking about deprecating append (see here)

Python has a number of libraries like Numpy, Matplotlib, and Pandas that are perfect for data science. Numpy is the basis for the Pandas library and also makes it easier to perform a lot of mathematical and statistical operations. Pandas, in turn, was created specifically to work with data and is perfect for data science work in Python.

FImage is a Python module to apply and create multiple filters to images, it exposes an API that you can use for applying the different color transformations to the images. It works by converting the image to an RGB matrix and applying different math formulas to it. We used NumPy for all the matrix operations since it is faster and optimized, and Pillow for handling the loading and saving of the images.

According to this https://github.com/numpy/numpy/releases it is supported
