This error statement TypeError: 'module' object is not callable is raised as you are being confused about the Class name and Module name. The problem is in the import line . You are importing a module, not a class. This happend because the module name and class name have the same name .
If you have a class "MyClass" in a file called "MyClass.py" , then you should import :
from MyClass import MyClass
In Python , a script is a module, whose name is determined by the filename . So when you start out your file MyClass.py with import MyClass you are creating a loop in the module structure.
