FYI - more info from interactive session, query configModuleObject and configModuleName using imp.find_module: >>> imp.find_module("configModuleObject") Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named configModuleObject >>> imp.find_module("a15800") (<open file 'a15800.pyc', mode 'rb' at 0x2b503b72d288>, 'a15800.pyc', ('.pyc', 'rb', 2)) >>> imp.find_module(configModuleName) (<open file 'a15800.pyc', mode 'rb' at 0x2b503b72d300>, 'a15800.pyc', ('.pyc', 'rb', 2)) -- https://mail.python.org/mailman/listinfo/python-list
