You can store the user's choice in a configuration file (like the ones supported by ConfigParser). Then you can put all the logic to select and import the right function in a separate module, and export the DNSLookup name; make all the other parts of the application say "from mymodule import DNSLookup" -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
