Wiki: http://www.orawiki.com/
Wikipedia: http://en.wikipedia.org/wiki/Oracle_database
license: commercial/proprietary; free for development from Oracle Technology Network; Oracle XE is free for production and development (and an excellent option all-around)
platforms: Unix, Linux, win32, win64

Pros

Reputation for being capable of handling large scale databases
Typically the database system others compare themselves to

Cons

Usually requires bloated Oracle client installation on any machine that the app will run on
Frequently the subject of migration discussions (to alternatives), usually for reasons of cost

DB API 2.0 Drivers

cx_Oracle

URL: http://cx-oracle.sourceforge.net/
licence: BSD like
platforms: Unix, win32
Python versions: 2.5 - 3.2

URL: http://www.zope.org/Members/matt/dco2
licence: ZPL
platforms: Unix, win32
Python versions
Last release: 1.3beta (Feb 10, 2003)

DCOracle2 targets Oracle 8i and up.

There also is DCOracle (http://www.zope.org/Products/DCOracle/) for the older Oracle 7 and 8 versions, but this is unmaintained.

mxODBC

URL: http://www.egenix.com/products/python/mxODBC/
Licence: eGenix Commercial License
Platforms: Windows, Linux, MacOS X, FreeBSD, Solaris, AIX
Python versions: 2.4 - 2.7

mxODBC is compatible with the Oracle ODBC drivers on Windows and Unix, such as the ones included in the Oracle Instant Client.

pyodbc

URL: http://code.google.com/p/pyodbc
License: MIT
Platforms: Windows, Linux, MacOS X, FreeBSD, Solaris, Any (source provided)
Python versions: 2.4 - 2.6

Actively maintained Open Source project.

Precompiled binaries are available for Windows. RedHat Enterprise Linux, Centos, and Fedora have precompiled RPMs available in their Extras repositories.

OJDBC and JayDeBeApi

URL: http://pypi.python.org/pypi/JayDeBeApi
licence: LGPL
platforms: Any (requires Java)
Python versions: Tested on CPython 2.6.6 and Jython 2.5.2
Oracle versions: Any supported by Oracle's JDBC drivers (currently 8.1.7 to 11.2.0.2.0)
Last release: 0.1 (2010-08-16)

No InstantClient required. Download an Oracle JDBC driver (the filename will be something like ojdbc6.jar) from the Oracle website, and set the classpath to include the driver. Note that if not running under Jython, JPype is required. Use code like the following:

   1 environ['JAVA_HOME'] = '/usr/lib/jvm/java-6-openjdk/jre'
   2 jpype.startJVM(jpype.getDefaultJVMPath(), '-Djava.class.path=ojdbc6.jar')
   3 conn = jaydebeapi.connect('oracle.jdbc.driver.OracleDriver', 'jdbc:oracle:thin:user/pass@server:1521:dbname')

Supported Python Applications

Zope
an Oracle (DCOracle and DCOracle2) driver exists for PyDO (Python Data Objects)
