Consider the vector [1, 2, 3, 4, 5] For example, suppose a is a huge intermediate result and the final result b only contains a small fraction of a, a deep copy should be made when constructing b with slicing: Functions and Methods Overview Here is a list of some useful NumPy functions and methods names ordered in categories
I will only go over a few of them in this tutorial That is, the addition of zero elements did not change the size of the sparse matrix

The goal of this collection is to offer a quick reference for both old and new users but also to provide a set of exercises for those who teach.
