Jun 26, 2012 · Eight queens problem is a constraint satisfaction problem. The task is to place eight queens in the 64 available squares in such a way that no queen attacks each other. So the problem can be formulated with variables x 1,x 2,x 3,x 4,x 5,x 6,x 7,x 8 and y 1,y 2,y 3,y 4,y 5,y 6, y 7,y 8; the xs represent the rows and ys the column. All Python code should have docstrings at the module, class and method level. Not every single method requires a docstring. Some method names are really well chosen, and little more needs to be said. Most times, however, documentation is essential for clarity. Python documentation is often written using the reStructuredText (RST) markup.
