Useful Modules, Packages and Libraries
The intent of this page is to list some of the most commonly used Python modules, in the hope that it will provide useful recommendations for other programmers (especially beginners). Remember that in addition to the listings below, there are other directories of Python modules - see PublishingPythonModules for details. Another collection of library details can be found on the ["Libraries"] page.
Be warned that this list is subjective by its very nature - it is only intended as a helpful guide. It is not definitive in any way, nor should it discourage developers from developing their own modules.
[http://sqlobject.org/ SQLObject] - Provides an object oriented way of accessing several different database systems
See also DatabaseProgramming for guidance.
Foreign Function Interface
[http://starship.python.net/crew/theller/wiki CTypes] - A package for calling the functions of dlls/shared libraries. Now included with Python 2.5 and up.
PyGtk - Bindings for the cross-platform Gtk toolkit.
PyQt - Bindings for the cross-platform Qt framework.
TkInter - The traditional Python user interface toolkit.
GUI Programming is, in many cases, a matter of taste. See a more extensive list on the GuiProgramming page.
[http://wwwsearch.sourceforge.net/ClientForm/ ClientForm] - "ClientForm is a Python module for handling HTML forms on the client side, useful for parsing HTML forms, filling them in and returning the completed forms to the server. It developed from a port of Gisle Aas' Perl module HTML::Form, from the libwww-perl library, but the interface is not the same." - from the website.
[http://www.crummy.com/software/BeautifulSoup/ Beautiful Soup] - HTML/XML parser designed for quick turnaround projects like screen-scraping, will accept bad markup.
[http://www.sacredchao.net/quodlibet/wiki/Development/Mutagen Mutagen] - Mutagen is a Python module to handle audio metadata. It supports FLAC, M4A, Musepack, MP3, Ogg FLAC, Ogg Speex, Ogg Theora, Ogg Vorbis, True Audio, and WavPack audio files. All versions of ID3v2 are supported, and all standard ID3v2.4 frames are parsed. It can read Xing headers to accurately calculate the bitrate and length of MP3s. ID3 and APEv2 tags can be edited regardless of audio format. It can also manipulate Ogg streams on an individual packet/page level.
[http://www.nedbatchelder.com/code/modules/id3reader.html ID3Reader] - "Id3reader.py is a Python module that reads ID3 metadata tags in MP3 files. It can read ID3v1, ID3v2.2, ID3v2.3, or ID3v2.4 tags. It does not write tags at all" (from site). Used in ID3Writer
[http://www.comfortableshoe.co.uk/cgi-bin/blosxom.cgi/Home/Python/id3Writer.comments ID3Writer] - Writes ID3 Tags for mp3s (both v1 and v2, as necessary). No Unicode support as of yet. Uses ID3Reader.
[http://sourceforge.net/projects/pyid3 PyID3] - ""(Appears to be inactive)""Module for manipulating ID3 informational tags in MP3 audio files. Not as good as ID3Writer, but no issues w/ genre, unlike ID3Writer.
[http://www.liquidx.net/pytagger/ pytagger] - tag reader and writer implemented purely in Python. Supports ID3v1, ID3v1.1, ID3v2.2, ID3v2.3 and ID3v2.4
[http://www.pythonware.com/products/pil/ Python Imaging Library (PIL)] - Supports many file formats, and provides powerful image processing and graphics capabilities.
Indexing and Searching
TwistedMatrix - Event-driven networking framework
[http://psyco.sourceforge.net/ Psyco] - Psyco can speed up the execution of any Python code (x86 only).
[http://pythonmac.org/wiki/py2app py2app] - Creates stand-alone apps (like py2exe for Mac)
[http://pyobjc.sourceforge.net PyObjC] - Bridge between the Python and Objective-C. Most important usage of this is writing Cocoa GUI applications on Mac OS X in pure Python
[http://www.py2exe.org/ Py2exe] - Converts python scripts into executable windows programs, able to run without requiring a python installation.
[http://code.enthought.com/chaco/ Chaco] - Creates interactive plots
[http://gnuplot-py.sourceforge.net/ gnuplot.py] - Based on gnuplot
[http://matplotlib.sourceforge.net/ Matplotlib] - Production quality output in a wide variety of formats
[http://pyx.sourceforge.net/ PyX] - Postscript and PDF output, (La)TeX integration
The SciPy [http://scipy.org/Topical_Software#head-b98ffdb309ccce4e4504a25ea75b5c806e4897b6 topical software] page has a longer list.
See RdfLibraries for a list of available RDF processing solutions.
[http://vpython.org/ Visual Python] - Offers real-time 3D output, is easily usable by novice programmers, excellent for physics.
[http://www.omegahat.org/RSPython/index.html Python Bindings for R] - R is a well known, open source (GPL 2) statistical package. RSPython provides the ability to access R from python, and vice-versa.
Standard Library Enhancements
[http://www.jorendorff.com/articles/python/path/ Python Path] - Wraps the functionality of the os.path module and provides something more convenient.
[http://chrisarndt.de/en/software/python/threadpool.html ThreadPool] - Intuitive approach to threads, well-explained.
[http://www.djangoproject.com Django] - High-level Python Web framework
[http://effbot.org/zone/element-index.htm ElementTree] - The Element type is a simple but flexible container object, designed to store hierarchical data structures, such as simplified XML infosets, in memory. --Note: Python 2.5 and up has ElementTree in the Standard Library--
[http://uche.ogbuji.net/tech/4suite/amara/manual Amara] - Amara provides tools you can trust to conform with XML standards without losing the familiar Python feel.
["PythonXml"] provides a list of available XML processing solutions.
Please avoid listing modules where...
- You are one of the developers (and you just want to promote your work somewhere).
- The modules in question do not have widespread approval or usage.
If you do want to make people aware of a module, package or library (perhaps your own), consider submitting it to one or more of the directories mentioned in PublishingPythonModules, perhaps also adding it to the topic-specific part of this site (eg. WebProgramming, GuiProgramming).
Do list modules that:
- Get recommended often in the Tutor or comp.lang.python lists
Please provide a short description for each module. Try to put each module in the category that matches its "main" audience, since a module might fall into a number of categories.
