The more I've learned about Python, The more I've heard about several external libraries that are available, and I was wondering what are some of your favorite python libraries that are availible.
A few of my favorites I've discovered:
so what are some of your favorites?
I also state PyGame but for another reason. I do use it for the occasional game development fix but I also find it very, very useful for all kinds of interactive and/or dynamic visualizations.
For my work it has to be numpy and scipy, with matplotlib coming in a close second. Traits and Pytables are also strong contenders!
import web)Parallel Python, for being the easiest way I've found to utilize multiple processor cores and distribute my data analysis tasks across multiple machines.
I'm partial to pysistence. Of course, that could have something to do with the fact that I wrote it.
I am going to nominate these:
And django, of course.
Two I commonly end up using are:
Suds - for SOAP related web service calls:

Psycopg - for Python-PostgreSQL database work:
My favorites are
Note: I use Werkzeug/SQLAlchemy/Jinja2/WTForms as a mix for MVC web development. We also use a light weight framework named Gypsy to tie those together.
Also I don't think I'd ever want to change my db scheme without SqlAchemy Migrations I can't express enough how much easier it makes my life when it comes to deployment time (or when it's time to revert!).
pyinotify allows you to write programs which react to changes in the filesystem. It can alert you when mail arrives, or recompile a program or TeX document every time it changes. It can process files as they are dropped into a directory.
pyinotify uses Linux's inotify mechanism, however, so it only works with Linux.
For building desktop GUI apps both wxPython and PyQt are excellent.
IMHO PyQt is more polished but is not open source for commercial use (it is for non-commercial use though).
Nokia (owners of Qt) are working on Pyside, a fully open-source competitor to PyQt.
I use PIL, python-twitter, django, simplejson, BeautifulSoup, and django-tagging often in projects. I highly recommend each of them.
Almost all my favorites have already been mentioned, but not yet some specialized ones such as pytz (best way to handle timezones) and pymox (for testing in the mock-objects way).
To add some that others have not mentioned:
To reiterate other packages:
For when you need to quickly read or write an Excel file, http://www.python-excel.org/ has some excellent modules. These modules don't require Windows or COM objects!
The ones I use frequently:
I use the following:
pyserial - cross-platform serial port access; simple to use and very stable. This should be added to the default python libraries!
pygtk - python interface for GTK+, an API for cross-platform GUI apps. Works great with Glade for rapid development and testing of user interfaces.
A lot of my favorites have already been mentioned.
Still I would like to nominate:
I use
also using wxPython, MySQLdb, and PIL too.
and sometimes built my own when speed does matter, with C/C++ - Extending Python with C or C++
pyquery: a jquery-like library for python
Although it's not complete yet, it makes writing screen scraping scripts a lot easier if you are already familiar with jQuery.
I work with data most of the time, and my must haves:
and for quite web prototyping,
Bottle.py
I'll throw in my 2 cents:
httplib2 - A comprehensive HTTP library, including auth, caching, all methods, redirects, compression, more. And, I can remember its API without looking up documentatiion. I can never remember exactly how urllib, urllib2 work
feedparser - very robust library for consuming RSS/Atom feeds
