Nice Code Formatting Conversion On Python Site

The documentation on the official Python site site has a nice little design feature in its code examples. Each one starts out formatted for Python's "interactive interpreter" and show the expected results. For example, this snippet from the Output Formatting section:

If you click the little ">>>" symbol in the upper left corner, the code instantly jumps to a format suitable for being run in a file. The expected out also disappears making the snippet ready to copy and paste directly into a file.

That's an incredibly useful feature. Very nicely done, Python doc crew.
