How do you print the size of an array in Python?
9 Answers. The number of rows of a list of lists would be: len(A) and the number of columns len(A) given that all rows have the same number of columns, i.e. all lists in each index are of the same size. Suppose you have a which is an array. to get the dimensions of an array you should use shape.
