Can someone tell me what this code does ?

I'm fairly new to Python so excuse my naiveté.

This code: in web/pgadmin/utils/driver/__init__.py does not appear to load
the drivers into the drivers dictionary ? Or am I missing something

def init_app(app):
drivers = dict()

setattr(app, '_pgadmin_server_drivers', drivers)
DriverRegistry.load_drivers()

return drivers
