4. String Services

The modules described in this chapter provide a wide range of string manipulation operations. Here's an overview:

string Common string operations.

re Regular expression search and match operations with a Perl-style expression syntax.

struct Interpret strings as packed binary data.

difflib Helpers for computing differences between objects.

fpformat General floating point formatting functions.

StringIO Read and write strings as if they were files.

cStringIO Faster version of StringIO, but not subclassable.

codecs Encode and decode data and streams.

unicodedata Access the Unicode Database.

Information on the methods of string objects can be found in section 2.2.6, ``String Methods.''
