An __init__.py to break classes up into single files without changing the import path.

__init__.py

# Import classes from files in the sub directory
# so files in models/ClassName.py with ClassName in it
# can be imported as models.ClassName

import pkgutil

__all__ = []

for _, name, ispkg in pkgutil.walk_packages(__path__):
    
    if not name.startswith('__') and not ispkg:
        # Ex: apps.assessment.models.<name>
        full_name = '.'.join([__name__, name])

        # Get the module that is holding the class
        module = __import__(full_name, fromlist=[name])
        
        # Get the class from the module and bring it into the global name space
        globals()[name] = getattr(module, name)
        
        # Add it to the __all__ array for * imports
        __all__.append(name)
