    <p>I am very new to python and have no idea what I'm doing but I am trying to learn as I program as this is what I have done in the past with C, C++, and Cocoa. </p> <p>I am writing a program with a matrix. I want to count the number of occurrences of x (x being a value in my matrix.) When I try to do this though I am not exactly sure what I am getting. A nice explanation of what I am getting and how to do things with matrices is all I am looking for. Eventually I will want to use the matrix.insert, the matrix.tofile, and the matrix.remove commands as well. Any sort of help is appreciated. </p> <p>Here is my Code:</p> <pre><code> matrix = [ [2, 9, 7, 5, 8, 9, 2, 4, 6], [8, 1, 1, 8, 4, 7, 5, 1, 3], [5, 5, 7, 7, 9, 3, 8, 1, 5], [1, 7, 8, 8, 2, 6, 4, 5, 9], [3, 8, 6, 3, 1, 7, 4, 9, 6], [9, 5, 4, 5, 9, 4, 2, 2, 3], [1, 2, 5, 9, 7, 9, 6, 1, 1], [7, 5, 8, 3, 2, 6, 9, 1, 5], [3, 1, 9, 6, 7, 8, 5, 3, 4], ] for sublist in matrix: S = str(sublist) print (S) for row in matrix: A = row.count(0) B = row.count(1) C = row.count(2) D = row.count(3) E = row.count(4) F = row.count(5) G = row.count(6) H = row.count(7) I = row.count(8) J = row.count(9) print (A) for row in matrix: if A &gt; 0: if B &lt; 1: print (B) </code></pre> <p>Here is what I get when I run the program:</p> <pre><code>[2, 9, 7, 5, 8, 9, 2, 4, 6] [8, 1, 1, 8, 4, 7, 5, 1, 3] [5, 5, 7, 7, 9, 3, 8, 1, 5] [1, 7, 8, 8, 2, 6, 4, 5, 9] [3, 8, 6, 3, 1, 7, 4, 9, 6] [9, 5, 4, 5, 9, 4, 2, 2, 3] [1, 2, 5, 9, 7, 9, 6, 1, 1] [7, 5, 8, 3, 2, 6, 9, 1, 5] [3, 1, 9, 6, 7, 8, 5, 3, 4] 0 0 0 0 0 0 0 0 0 </code></pre> <p>Thank You!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
