WebPython Matrix. Python doesn't have a built-in type for matrices. However, we can treat a list of a list as a matrix. For example: A = [[1, 4, 5], [-5, 8, 9]] We can treat this list of a list as a matrix having 2 rows and 3 columns. … WebMay 9, 2024 · Adjacency matrix of a weighted graph. In Python, we can represent graphs like this using a two-dimensional array. And a two-dimensional array can be achieved in Python by creating a list of lists.
