Write a plugin-based wxpython application

The following code will get a listing of .py files then import them.
You may want to wrap each import in a try/except to delete the module
from sys.modules if loading failed.

    plugin_path = ...
    plugin_name = ...

    x = [i[:-3] for i in os.listdir(plugin_path)
           if i.endswith('.py') and and i.count('.')== 1
              and i != '__init__.py']

    for plug_name in x:
        gl = globals()
        pl = gl[plug_name] = __import__('%s.%s'%(plugin_name, plug_name))
        #do whatever you need to do to the plugin pl here

Maby thanks for your quick answer…
So should be relatively simple write for example two macro-plugins like two
directories (viewed in the menu-bar), and then a suite of sub-plugins stored
in files (for example the voices of the sub-menu)
My idea is to create two or more folders like this:

That that would be easy.

src/plugin1/
sub-pluign1.py
sub-plugin2.py

That is fine, except that sub-plugin1, etc., should be named
sub_plugin1.py, etc., and there must be an init.py so that it can be
imported via: import plugin1.sub_plugin1 .

So in the menubar i could have Plugin1 and Plugin2 like two buttons, and the
sub-plugins like voices of the menu buttons.
Have you understand my idea?

That is possible, but you need to define an interface for how plugins
interact with your menu bar, frames, etc.

My question now is this:

How do I define an interface for how plugins interact with menu items, frames etc, etc?

Please can anyone share a sample code for this?

Thanks.

That is fine, except that sub-plugin1, etc., should be named
sub_plugin1.py, etc., and there must be an __init__.py so that it can be
imported via: import plugin1.sub_plugin1 .
