New python 3 modules

[evstevemd]

I started this for any information on new python modules apart from standard library. Many people (Including me), aren't willing to move into p3k due to lack of external/non-standard modules.

So I started this to keep ourselves informed on New Python 3 Modules.
No Limitation, ANY PYTHON 3 MODULE

Like I mentioned in another thread, the problem is that a lot of those modules are freeware done by different folks. Monetary reward is more of a driving force, and it will take a while to get those free things to show up. Python30 has a lot of rather subtle changes that need to be considered to avoid buggy code.

Well i know this may be obvious, but Tkinter is all ready to be used in python 3. So anybody who uses that GUI toolkit will still be able to use it in python 30.

Tkinter ships with the Python30, it better work! Also Tkinter uses its own language called TCL, so changes would have been minor.

Anyway evstevemd, a good idea to keep an eye out for some of those popular open-source modules to appear.

Yeah, I understand!
I wanted us to keep each other updated in case any module comes for python 3

Nice idea! Will keep checking it for the next year or so.

Mark Pilgrim is preparing his Book dive into python 3. He isn't finished yet and I thought I should publish here for someone to watch

Well i think i can post the first one. Beautiful Soup!

All you need to do is an automatic python 3 conversion on it and then it works fine with python 3. So enjoy :)

Cython, for writing extension modules works with Python 3. One of the great things about it is that extension modules you write with it work for both Python 2.x and Python 3.x most of the time, without adjustment.

[woooee]

SQLite is also packaged with Python 3.x. PostgreSQL has pg8000-py3. Don't know about MySQL or any of the others.

This will not work! Python30 does not have a module called 'sgmllib'. The error is:
Traceback (most recent call last):
File "", line 248, in run_nodebug
File "C:\Python30\Atest30\Bull\BS_ParseHtml1.py", line 4, in
from BeautifulSoup import BeautifulSoup
File "C:\Python30\Atest30\Bull\BeautifulSoup.py", line 54, in
from sgmllib import SGMLParser, SGMLParseError
ImportError: No module named sgmllib

Well it must somehow, the site says it does and im sure they wouldnt say that without some foundation at least.

http://www.crummy.com/software/BeautifulSoup/ says
Beautiful Soup is known to work with Python versions 2.4, 2.5, and (after an automatic conversion) 3.0. Currently the 3.0.x series is better at parsing bad HTML than the 3.1 series.

from: http://www.crummy.com/software/BeautifulSoup/3.1-problems.html

In Python 3.0, the latest version of Python, SGMLParser has been removed. The only parser that's part of the Python 3.0 standard library is HTMLParser, a simpler parser that's much worse at processing malformed HTML.

In the meantime, an excellent new HTML parsing library called html5lib has emerged. It's very good at processing malformed HTML, but it's not part of the Python standard library, and at the moment it's slower than either SGMLParser or HTMLParser.

I no longer enjoy working on Beautiful Soup, but too many people depend on it for me to let the project die just because it depends on code that's been removed from the Python standard library. So I wrote Beautiful Soup 3.1.0, which cleans up the Python 2.x code so that it can be automatically converted to Python 3.0. code. Part of this change was to switch the underlying parser from SGMLParser to HTMLParser. The errors you're seeing are caused by HTML that SGMLParser could handle but HTMLParser can't.

When Beautiful Soup was first released in May of 2004, there were no lenient HTML parsers that were easy to program, only the ones embedded in web browsers. Now there are lots of programmable lenient HTML parsers, and most of them are better than SGMLParser, let alone HTMLParser. These days, Beautiful Soup is useful for its Unicode handling and its tree-traversal methods. Parsing is longer a competitive advantage for Beautiful Soup, and I'd be happier if I could get out of the parser business altogether.

What I gather from this is that the author of the library no longer wants to continue develop BeautifulSoup, and since python 3 it's become worse at parsing real world html (malformed html). Even if the code can be converted into working python 3 code, it's probably a good idea to start looking for other parsers.

I've found a couple of blogs that points to lxml as the parser of choice. Take a look at http://blog.ianbicking.org/2008/03/30/python-html-parser-performance/

BeautifulSoup works fine with Python30 if you
copy
BeautifulSoup.py (version3.0.7a or lower)
and
sgmllib.py (find it typically in C:\Python25\Lib)
to a separate directory and convert both programs with 2to3.py

This rather obvious approach was overlooked by the BeautifulSoup folks.

Win32 Extensions for Python from:

is available in it's Python3 version, see:
http://sourceforge.net/project/showfiles.php?group_id=78018
and download and install:
pywin32-213.win32-py3.0.exe

PyQT is out for QT fans.
It is in pyQT 4.5
For more, see here:

wxPython isn't yet out and I asked on the mail list, there is no nearby plan to port it to 3k. So Stick with your python 2.x version.

I also hope haven't missed any module apart from mentioned above
