How did you import the class? Or did you perhaps not import the Class itself, but rather the module containing the class? Read this article which explains a bit about Python namespaces: http://is.gd/e8PAZW (but I note there's a bit of conflation of "class" and "class instance" going on at the end.) Also read this page from the Python documentation, section "Python Scopes and Namespaces": http://docs.python.org/tutorial/classes.html If a class is defined in a module (e.g. in the namespace of the module), and you "import module" the module into the your current namespace, then from within the current namespace you can access the class with "module.Class". If however you import the class itself, e.g. "from module import Class", into your current namespace, then the Class itself is directly part of your local namespace and you must therefore access it unqualified as just "Class".
