NumPy 数组裁切 - w3school 在线教程

裁切数组 python 中裁切的意思是将元素从一个给定的索引带到另一个给定的索引。我们像这样传递切片而不是索引：[start：end]。我们还可以定义步长，如下所示：[start：end：step]。如果我们不传递 start，则将其视为 0。如果我们不传递 end，则视为该维度内数组的长度。

Indexing on ndarrays — NumPy v2.2 Manual

NumPy slicing creates a view instead of a copy as in the case of built-in Python sequences such as string, tuple and list. Care must be taken when extracting a small portion from a large array which becomes useless after the extraction, because the small portion extracted contains a reference to the large original array whose memory will not be released until all arrays derived from it are ...
