This is a page that is devoted to short programs that can perform powerful opperations. The ability to write short programs that are just as powerful as a program written in another lanuage designed to do the same thing. However, it is sometimes fun to try and write a program in Python that is only one line. In other lanugages this would be nearly ''impossible'', but in Python it is a lot easier to do. The trick is to think up something that will "do a lot with a little." I, personally, would love to see this page expanded to the point where it needs some sort of organization system. |

| My opinion is that this form is far more readable and clear. I propose that, rather than go for one-liners, rather go for "powerful code snippets", where we don't try to squeeze stuff into one-line just for its own sake. Thoughts on this, anyone? CalebHattingh ---- |
