...Have a place for plugins
app/plugins
...Load the plugins on startup
import traceback
import os
for fn in os.listdir('plugins'):
if fn[:1] != '_' and fn.split('.')[-1] in ('py', 'pyw'):
try:
globals()[fn] = \
__import__('plugins.%s'%fn, globals(), locals(), [fn])
except:
traceback.print_exc()
Etcetera. May not be the best, but it will get the job done.
