    <p>You're testing for equality, but not doing anything with it, with those <code>==</code>. What you need is something like:</p> <pre><code>def ant_coordinates(ant_row, ant_col, orientation): color = orig_grid[ant_row][ant_col] if color == 'white': if orientation == 'East': ant_row += 1 elif orientation == 'South': ant_col -= 1 return ant_row, ant_col, orientation </code></pre> <p>I'm not sure what the actual behavior of this function is supposed to be, but what it will do is:</p> <p>If color is not white, just return all of the parameters unchanged.</p> <p>If color is white and orientation is east, return all of the parameters with row += 1. </p> <p>If color is white and orientation is south, return all of the parameters with col -= 1. </p> <p>If color is white and orientation is other, return all parameters unchanged. You can obviously extend this function to add functionality for other directions.</p> <p>What your code does now is:</p> <pre><code>def ant_coordinates(ant_row, ant_col, orientation): color = orig_grid[ant_row][ant_col] if color == 'white': # goes in here if color is white orientation == 'East' # returns True or False, value not used anywhere ant_row += 1 # always increments row if color is white orientation == 'South' # returns True or False, value not used anywhere ant_col -= 1 # always decrements col if color is white return ant_row, ant_col, orientation </code></pre> <p>Hope this helps! <code>==</code> is just a comparison, it doesn't imply an <code>if</code>.</p>

    1. COI think (without looking at the problem) that the OP might want "=" instead for `orientation ==`.

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.
