How would you write pseudocode for drawing an 8-by-8 checkerboard of squares, where none of the squares have to be full? (Can all be empty) I don't quite get the pseudocode concept.

Think of writing pseudocode like you would explain it to another person - it doesn't generally have to conform to any particular syntax as long as what's happening is clear to the grader.

I would be even more generic eg.

Loop with x from 1 to 8 Loop with y from 1 to 8 draw square at x, y

Wikipedia articles use Pseudocode a lot, quite successfully. There is no standard for Pseudocode on wikipedia, and syntax varies, but here is some general information with examples: Algorithms on Wikipedia

Here are two good examples of articles with Pseudocode (more):

Using Wikipedia-like style, I'd do:

for i from 0 to 7 for j from 0 to 7 if (i + j) is even then paint square (i, j) black else paint square (i, j) white

(Marking end of if or end of for with 'end if' or 'repeat'/'end for' is a matter of style I guess).

Pseudo code is writing out the code in form that is like code but not quite code. So for opening a file and printing printing out its lines of text

if file exists(path_to_file) then : open (path_to_file) for each line in file : print the line of the file

All you should do is create the sequence of steps needed for your problem and write it out like that. Since you mention python, just use use a more python like syntax in your pseudo code.

I suspect that you problem will be to encourage you to consider how to make functions and classes, and writing the pseudo code first will help you do this.
