This is close to beeing trivial in python - just utilize __import__ to
dynamically load modules that shall act as plugins. These modules then only
have to follow a sort of protocol - lets say you have a module called

pluginloader.py

that has a register-function. The loaded module could import pluginloader
and register itself, or a class defined in itself. Like this

---------plugin_example.py-------------

import pluginloader


class ExamplePlugin(pluginloader.PluginBase):
     def __init__(self,...):
         ....



pluginloader.register(ExamplePlugin())
