Super Simple Python Plugins is a minimal framework for implementing plugins in Python programs. There's no setup or anything, just create a directory and put the init.py file in it (turning the directory into a module). Any Python source files placed in that directory will be automatically loaded when the module is loaded. The names of the plugins will be put in the all list variable. Beyond that, you can do anything you want with the plugins.

Here's an example of how to use it. Let's assume that there is a single plugins directory, named (logically enough) 'plugins'. Submodules should define a callable object named 'register' that will be invoked when the plug-in is loaded, but it's not required.

import plugins

for name in plugins.__all__:
    plugin = getattr(plugins, name)
    try:
        plugin.register()
    except AttributeError:
        # raise an exception, log a message, 
        # or just ignore the problem
        pass
