Hello, Sub class test fails. ====================== I have a program that needs to load plugin-classes during runtime.
The program has these subdirectories (modules). $ tree . `-- test.py | |-- plugins | |-- base_plugin.py | |-- base_plugin.pyc | |-- __init__.py | `-- oca | |-- __init__.py | |-- open_clipart.py The plugins (sub directory) contains one or more plugin modules, in this test-case there is only one; oca/open_clipart.py. The plugins/base_plugin.py (contains class Plugin()) is a base class of all plugins. I want to list and load all plugin-classes (that inherit from base_plugin.Plugin). I have a Python code that successfully browses the plugins, but the the test issubclass(x, base_plugin.Plugin) fails. Please see this Python code: http://futuredesktop.com/tmp/test6.tar.gz Why the issubclass(entry, cls) test fails? if issubclass(entry, cls): ....print "Found a subclass: " + key ....subclasses.append(entry) I can see that the class names are right, even objects of these classes are ok. My OS is Ubuntu 10.04. $ python --version Python 2.6.5 The actual, final product will be this http://www.futuredesktop.com/clipart-applet/clipart-applet.ogv It is a ClipArt query-engine and browser. It can translate queries from "any" language to english ;-) Most kindly Osmo Antero Maatta Grønland, Oslo -- http://mail.python.org/mailman/listinfo/python-list
