You can start with this article that I wrote in Heartbeat magazine (on Medium platform):
Jupyter notebooks covering a wide range of functions and operations on the topics of NumPy, Pandans, Seaborn, Matplotlib etc.
- Detailed Numpy operations
- Detailed Pandas operations
- Numpy and Pandas quick basics
- Matplotlib and Seaborn quick basics
- Advanced Pandas operations
- How to read various data sources
- PDF reading and table processing demo
- How fast are Numpy operations compared to pure Python code? (Read my article on Medium related to this topic)
- Fast reading from Numpy using .npy file format (Read my article on Medium on this topic)
Tutorial-type notebooks covering regression, classification, clustering, dimensionality reduction, and some basic neural network algorithms
