Indexing on ndarrays — NumPy v2.2 Manual
Note. 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 ...

python - Index of element in NumPy array - Stack Overflow
This problem can be solved efficiently using the numpy_indexed library (disclaimer: I am its author); which was created to address problems of this type. npi.indices can be viewed as an n-dimensional generalisation of list.index. It will act on nd-arrays (along a specified axis); and also will look up multiple entries in a vectorized manner as opposed to a single item at a time.

NumPy Array Indexing - W3Schools
Array indexing is the same as accessing an array element. You can access an array element by referring to its index number. The indexes in NumPy arrays start with 0, meaning that the first element has index 0, and the second has index 1 etc.

Numpy Array Indexing (With Examples) - Programiz
The number is known as an array index. Let's see an example to demonstrate NumPy array indexing. Array Indexing in NumPy. In the above array, 5 is the 3rd element. However, its index is 2. This is because the array indexing starts from 0, that is, the first element of the array has index 0, the second element has index 1, and so on.

NumPy Array Indexing - Python Tutorial
Summary: in this tutorial, you’ll learn how to access elements of a numpy array using indices.. Like a list, you can use the square bracket notation ([]) to access elements of a numpy array.. NumPy array indexing on 1-D arrays #. Along a single axis, you can select elements using indices. The first element starts with index 0, the second element starts with index 1, and so on.

Indexing in NumPy - Online Tutorials Library
Negative Indexing in NumPy. We use negative indexing to access elements from the end of an array. The index -1 refers to the last element in the array, -2 refers second last, and so on. It is mostly useful for accessing elements in reverse order in multi-dimensional arrays. Example . Following is an example of the negative indexing in NumPy −

Basic Slicing and Advanced Indexing in NumPy - GeeksforGeeks
Let's discuss different methods to perform indexing in the NumPy array: Indexing Using Index arrays. Indexing can be done in NumPy by using an array as an index. Numpy arrays can be indexed with other arrays or any other sequence with the exception of tuples. The last element is indexed by -1 second last by -2 and so on.

Indexing — NumPy v1.21 Manual
The native NumPy indexing type is intp and may differ from the default integer array type. intp is the smallest data type sufficient to safely index any array; for advanced indexing it may be faster than other types. For advanced assignments, there is in general no guarantee for the iteration order.
