All of the examples have a link on the left column pointing to the source code. Using Netscape, follow the link to open the file. There are some instructions and examples in the header of each file which you may want to read. Save the file to your local machine, and run it. It should be run as "python filename", where 'filename' is the name you save it as.

Enjoy! And ask me any questions you might have about PyDaylight.
