How about something like this in fruit/__init__.py: import os fruit_dir = os.path.dirname(__file__) fruit_files = [x for x in os.listdir(fruit_dir) if (x[-3:]=='.py' and x!='__init__.py')] for fruit_file in fruit_files: module_name = fruit_files[:-3] exec "from %s import *" % module_name HTH, Carsten. -- http://mail.python.org/mailman/listinfo/python-list
