Introduction to Numpy Multidimensional Arrays

When working with data in Python, the need for multidimensional arrays often arises, especially in scientific computing and data analysis. A common scenario is to create an array with a specific shape, say (x, y), filled with consecutive values. How can you achieve this with minimal effort without resorting to lengthy loops? This guide will walk you through a straightforward solution using the powerful Numpy library in Python.

Understanding the Problem

Suppose you want to create a 2D array with dimensions (x, y) filled with numbers ranging from 0 up to z-1, where z is the total number of elements in the array. Rather than randomly generating values, you require a structured array that displays a sequence of numbers.

For example:

If x = 5 and y = 3, you wish to create an array shaped like this:

Enter Numpy

The Solution: Using Numpy Functions

Step 1: Import Numpy

Before we can use the functions, we need to ensure that Numpy is imported. This can be done with the following command:

Step 2: Define Your Dimensions

Define the variables x and y to set the height and width of your array, respectively. These can be any two integers based on your specific requirements. In our example:
