## How to add dimension to Numpy array?

Let’s check how to add a dimension to a Numpy array. Expanding dimensions in a NumPy array can be a valuable operation when working with multidimensional data. We will use the newaxis and expand_dims functions.

## How to stack arrays in Numpy?

In this tutorial, we’ll explore how to stack arrays in the NumPy Python library. Stacking arrays is a fundamental operation in data manipulation, often used to combine data from different sources or manipulate multi-dimensional data. NumPy provides several functions for stacking arrays, allowing you to customize the stacking process based on your needs.

## How to rank values in Numpy array?

Let’s check how to rank values in a Numpy array by axis.
