The main program can insert the plugins directory into sys.path and
import at will (e.g with __import__) or do it with the imp module or in
several other ways. There's a number of recipes in the cookbook...

Thanks.....
I use a simple method...

sys.commands module --> get file list
re module --> filter file name and path
imp module --> load module
getattr() --> get varabiles

because none dll for unix, I don't know how to use *.pyd
and how to make *.pyd from *.py

Not sure what you mean by "because none dll for unix". A *.pyd on
Windows is a DLL (meant for Python extension); you cannot make it from a
*.py, you make it from a *.c or the like. Equivalent on different Unix
variants are *.so, *.dynlib, and others yet.
