As the @ryklwa is a project, which not the only person works for, we can write about wide bunch of different subjects.
For now, I would like to present you an useful list of libraries for doing Data Science in Python. This list is placed in my personal Github repo. Preferably, I'd copy and paste it here, but I don't want to be accused of plagiarism 😝.
So, I just leave here an URL:
https://github.com/krzjoa/awesome-python-datascience
Keep in mind, that this list is still growing! Do you know another awesome Python libs, which not are mentioned here?
