1) Don't use the name 'str', you're shadowing a built-in name. 2) Use __import__ to import a module with a variable name. 3) Use getattr to look up an attribute with a variable name. Putting 1-3 together, you get code something like this: module_name = "module" mod = __import__(module_name) class_name = module_name.capitalize() cls = getattr(mod, class_name) inst = cls() Hope this helps, Carsten. -- http://mail.python.org/mailman/listinfo/python-list
