Supply a plugin interface

[Johannes Bauer]

Hello group,

I'm developing a GUI application in Python and having a blast so far :-)

What I'd like to add: I want the GUI users to supply plugin scripts,
i.e. offer some kind of API. That is, I want the user to write short
Python pieces which look something like

import guiapp

class myplugin():
	def __init__(self):
		guiapp.add_menu("foobar")

	def exec(self, param):
		print("foo")

the GUI application should now browse the plugin directory and read
those plugin python files and somehow incorporate (i.e. discover what
modules are there, instanciate, etc.)

How do I do that at runtime with Python?

Kind regards,
Johannes
