Chapter 9. Strings and Regular Expressions
Python supports plain and Unicode strings extensively, with
statements, operators, built-in functions, methods, and dedicated
modules. This chapter covers the methods of string objects, talks
about string formatting, documents the string,
pprint, and repr modules, and
discusses issues related to Unicode strings.
Regular expressions let you specify pattern strings and allow
searches and substitutions. Regular expressions are not easy to
master, but they are a powerful tool for processing text. Python
offers rich regular expression functionality through the built-in
re module, as documented in this chapter.
