Import class from module dynamically

by

It is expecting my_module to be a package containing a module named 'my_class'. If you need to import a class, or an attribute in general, dynamically, just use getattr after you import the module:

cls = getattr(import_module('my_module'), 'my_class')

Also, yes, it does only work with modules. Remember importlib.import_module is a wrapper of the internal importlib.__import__ function. It doesn’t offer the same amount of functionality as the full import statement which, coupled with from, performs an attribute look-up on the imported module.
