Numeric Python

- Basics of solving numerical problems with Python - Processing large amounts of data with NumPy, e.g. in machine learning - Data visualization with Matplotlib - Ideal for people in science, engineering and data analysis - Ideal for switching from Matlab to Python - Introduction based on many examples and practical cases as well as sample solutions This book teaches the Python basics for solving numerical problems in the areas of data science and machine learning. The first part is about NumPy as the basis for numerical programming with Python. Arrays are covered in detail as the central data type for everything, numerical operations, broadcasting and Ufuncs. A separate chapter is devoted to statistics and probability, as well as Boolean masking and file handling. Data visualization with Matplotlib is the focus of the second part. First of all, it's about the terminology of Matplotlib. Line charts, bar charts, histograms and contour plots are covered. The third part is about Pandas with its Series and DataFrames. Dealing with a wide variety of file formats such as Excel, CSV and JSON as well as incomplete data and NaN is also covered. The possibilities of data visualization directly with Pandas are shown. The fourth part offers example applications of the material learned, such as a budget book and a practical income surplus calculation. There is also an introduction to image processing techniques here. Almost each of the 32 chapters contains additional exercises to test and deepen what you have learned; the associated solutions are summarized in the fifth part.
