SQLObject is an object-relational mapper, i.e., a library that will wrap your database tables in Python classes and your rows in Python instances. It currently supports MySQL through the 'MySQLdb' package, PostgreSQL through the 'psycopg' package, SQLite, Firebird, MaxDB (SAP DB), MS SQL, and Sybase. It should support Python versions back to 2.4.
Python bsddb3 is a Python module that provides a nearly complete wrapping of the Oracle/Sleepycat C API for the database environment, database, cursor, sequence, and transaction objects, and each of these is exposed as a Python type in the bsddb3.db module. The database objects can use various access methods: btree, hash, recno, and queue. It has complete support for Berkeley DB distributed transactions, and complete support for the Berkeley DB Replication Manager and base replication API. The goal is to mirror most of the real Berkeley DB API.
pyratemp is probably (one of) the smallest complete template-engines for Python (with about 500 LOC). It has a very small set of special syntax in the templates. This reduces complexity and the probability of bugs and lead to an easy-to-use and intuitive user-interface. It uses embedded Python-expressions (in a "sandbox"), is well documented, has full Unicode-support, and produces very good error-messages, which is very useful when creating new templates.
Fivebit is a Python 3 compression library for short text strings. It compresses short strings of text into five bit encoding, which yields a 37.5% reduction for lowercase ASCII. There is also a dictionary for the 1024 most common English words (3 letters or longer). Punctuation, digits, and normal symbols will usually take up 10 bits each, and oddball Unicode characters will take up more space again.
python-stdnum is a Python module to parse, validate, and reformat standard numbers and codes in different formats. It supports a large number of number formats, including: ISBN (International Standard Book Number), ISSN (International Standard Serial Number), BSN (Burgerservicenummer, the Dutch national identification number), EAN (International Article Number), SSN (U.S. Social Security Number), IMEI (International Mobile Equipment Identity), IBAN (International Bank Account Number), and more.
Cedar Backup is a software package designed to manage system backups for a pool of local and remote machines. Cedar Backup understands how to back up filesystem data as well as MySQL and PostgreSQL databases and Subversion repositories. It can also be easily extended to support other kinds of data sources. Cedar Backup is focused around weekly backups to a single CD or DVD disc. It supports multisession discs, allowing you to add incremental data to a disc on a daily basis. Cedar Backup also provides a Python library of backup-related functionality.
GeoTypes is a Python library that implements both the OpenGIS/PostGIS and standard PostgreSQL geometry types. It integrates with the psycopg Python/PostgreSQL interface. It provides implementations of all of the OpenGIS/PostGIS classes, except (x,y,m) and (x,y,z,m). It currently supports the EWKB, HEXEWKB, WKB, and WKT formats.
Python Audio Tools is a collection of audio handling programs that work from the command line. These include programs for CD extraction, track conversion from one audio format to another, track renaming and retagging, track identification, CD burning from tracks, and more. It supports internationalized track filenames and metadata using Unicode. It works with high-definition, multi-channel audio as well as CD-quality. Track conversion uses multiple CPUs or CPU cores if available to greatly speed the transcoding process. Track metadata can be retrieved from MusicBrainz, FreeDB, or compatible servers. Audio formats supported are WAV, FLAC, WavPack, MP3, Ogg Vorbis, M4A, Apple Lossless, and more.
