A matrix may be implemented as a hierarchical **list in Python** (**list inside** a **list**). Each element may be thought of as a row in the matrix. A 3x2 matrix would be represented as X = [[1, 2], [4, 5], [3, 6]]. The element in the first row, first column may be chosen as X[0], and the element in the first row, first column can be selected as X[0].
