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

Specify with a list of integers: fancy indexing. It is also possible to select ranges with a list or ndarray of integers. Example with a 1D array: Order can be inverted or repeated, and using negative values is allowed. Essentially, it involves creating a new array by selecting specific positions from the original array.

NumPy Array Slicing - W3Schools

Slicing arrays. Slicing in python means taking elements from one given index to another given index. We pass slice instead of index like this: [start:end]. We can also define the step, like this: [start:end:step]. If we don't pass start its considered 0. If we don't pass end its considered length of array in that dimension
