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.

reconvert Convert regex-, emacs- or sed-style regular expressions to re-style 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.

textwrap Text wrapping and filling

codecs Encode and decode data and streams.

encodings.idna Internationalized Domain Names implementation

unicodedata Access the Unicode Database.

stringprep String preparation, as per RFC 3453

Information on the methods of string objects can be found in section 2.3.6, ``String Methods.''
