python - I want to select specific range of indexes from an array ...

This will return the 2nd, 4th, 6th, and 8th array elements (keeping in mind that python indices start from 0). So, if you want every 2nd element starting from an index x, you can simply populate a list with those elements and then feed that list into the array to get the elements you want, e.g:

Array Indexing in Python - Beginner's Reference - AskPython

Python Array Index (Multi-dimensional Arrays) Indexing a multi-dimensional array is quite complex. Let us start with creating a simple multidimensional array. For creating a multidimensional array we will use reshape() and arange() methods. The reshape() function takes a single argument that specifies the new shape of the array. The arange() method is used in Numpy. It takes to start and end arguments and creates a single dimension array.

NumPy: Get and set values in an array using various indexing

You can use range() to achieve similar functionality as slices. For example, to simulate slicing, retrieve the size of the target dimension using the shape attribute and pass it to range() as in range(a.shape[n])[::]. How to use range() in Python; NumPy: Get the number of dimensions, shape, and size of ndarray

Indexing — NumPy v1.21 Manual

An integer, i, returns the same values as i:i+1 except the dimensionality of the returned object is reduced by 1. In particular, a selection tuple with the p-th element an integer (and all other entries :) returns the corresponding sub-array with dimension N - 1.If N = 1 then the returned object is an array scalar. These objects are explained in Scalars.. If the selection tuple has all entries : except the p-th entry which is a slice object i:j:k, then the returned array has dimension N ...
