WebA 2D array in python is a two-dimensional data structure stored linearly in the memory. It means that it has two dimensions, the rows, and the columns, and thus it also represents a matrix. By linear data structure, we mean that the elements are linearly placed in memory, and each element is connected to its previous and next elements.
