2016-11-09 22:00:46 +0200 | asked a question | How to create a row that displays the counts of column entries in a matrix using python/sage? so here is my matrix: I would like to insert a 0 row that displays the amount of row entries in each column. This was my original code: puzzle = A.insert_row(0, sum(A)) Whats wrong with this code is that it gives me the sum of each column, when I just need the count of each column. What I have Desired |
