## 5.10. Summary

That's it for the hard-core object trickery. You'll see a real-world application of special class methods in Chapter 12, which uses `getattr` to create a proxy to a remote web service.

The next chapter will continue using this code sample to explore other Python concepts, such as exceptions, file objects, and `for` loops.

Before diving into the next chapter, make sure you're comfortable doing all of these things:

- Importing modules using either `import module` or `from module import`
- Defining and instantiating classes
- Defining `__init__` methods and other special class methods, and understanding when they are called
- Subclassing `UserDict` to define classes that act like dictionaries
- Defining data attributes and class attributes, and understanding the differences between them
- Defining private attributes and methods
