where is the new sockets library

The web site says that the Python sockets library has been extended. Where do I download that extension? My sockets library does not have any reference to XBee.

What web site are you referring to?

The following web site
https://www.digi.com/wiki/developer/index.php/XBee_Extensions_to_the_Python_socket_API
describes “new” extensions to the python socket library to accomodate Zigbee devices.

Where do I download these extensions? My existing python socket library does not recognize the new constants (e.g. AF_XBEE) in the revised socket library so clearly I do not have the correct extensions installed.

I did download the XBEE-2.2.3 module and installed it but there are no modified socket classes in that package.

By the way, I am obligated to do this project in Python3.
