This document discusses Python's import statement and provides examples of using __import__ for dynamic loading of modules. It demonstrates how to import a module string dynamically using __import__ when a module name is stored in a variable. It also shows how to import specific functions from a module using __import__'s fromlist parameter. The document provides references for further information on import, __import__, and reloading modules in Python.
