Indexing
ndarrays can be indexed using the standard Python x[obj] syntax, where x is the array and obj the selection. There are three kinds of indexing available: field access, basic slicing, advanced indexing. Which one occurs depends on obj.
Note

Basic Slicing and Indexing
Basic slicing extends Python’s basic concept of slicing to N dimensions. Basic slicing occurs when obj is a 登录查看完整内容
