   What is a matrix in Python?

   • A matrix is a two-dimensional data structure where numbers are arranged into rows and columns. For example: This matrix is a 3x4 (pronounced "three by four") matrix because it has 3 rows and 4 columns. Python doesn't have a built-in type for matrices. However, we can treat a list of a list as a matrix. For example: [-5, 8, 9]]

   Can nested lists be used as matrices in Python?

   • Using nested lists as a matrix works for simple computational tasks, however, there is a better way of working with matrices in Python using NumPy package. NumPy is a package for scientific computing which has support for a powerful N-dimensional array object. Before you can use NumPy, you need to install it. For more info,

   How to transpose a matrix using loop in Python?

   • Example: Python Program to Transpose a Matrix using loop Transpose of a matrix is obtained by changing rows to columns and columns to rows. In other words, transpose of A is obtained by changing A [i] [j] to A [j] [i]. Output: Create a matrix using Numpy Here we are creating a Numpy array using numpy.random and a random module. Output:

   What are matrices used for?

   • In the fields of engineering, physics, statistics, and graphics, matrices are widely used to express picture rotations and other types of transformations. The matrix is referred to as an m by n matrix, denoted by the symbol “m x n” if there are m rows and n columns. Method 1: Creating a matrix with a List of list
