Chapter Summary

This chapter explored advanced string types available in Python 3.0 and 2.6 for processing Unicode text and binary data. As we saw, many programmers use ASCII text and can get by with the basic string type and its operations. For more advanced applications, Python’s string models fully support both wide-character Unicode text (via the normal string type in 3.0 and a special type in 2.6) and byte-oriented data (represented with a bytes type in 3.0 and normal strings in 2.6).

In addition, we learned how Python’s file object has mutated in 3.0 to automatically encode and decode Unicode text and deal with byte strings for binary-mode files. Finally, we briefly met some text and binary data tools in Python’s library, and sampled their behavior in 3.0.

In the next chapter, we’ll shift our focus to tool-builder topics, with a look at ways to manage access to object attributes by inserting automatically run code. Before we move on, though, here’s a set of questions to review what we’ve learned here.
