2D Array in Python is an array of arrays. It is also called Matrix. Learn how to create, access, update and delete elements of a 2D array in Python.
You might hear of a 0-D (zero-dimensional) array referred to as a “scalar”, a 1-D (one-dimensional) array as a “vector”, a 2-D (two-dimensional) array as a “matrix”, or an N-D (N-dimensional, where “N” is typically an integer greater than 2) array as a “tensor”.
How to initialize a two-dimensional array in Python? You can use the built-in list function to create a 2D array (also known as a list of lists) in Python. Here is an example of how to create a 2D array with 3 rows and 4 columns, filled with zeroes:
