See the rlcompleter module in the standard library:
http://docs.python.org/library/rlcompleter.html
In my .bashrc file, I have a line:
[ -f ~/.pythonrc ] && export PYTHONSTARTUP=~/.pythonrc
and in the .pythonrc file, I include:
try:
import readline
except ImportError:
print("Module readline not available.")
else:
import rlcompleter
readline.parse_and_bind("tab: complete")
Note the print() form which works with either Python 2 or 3.

Why IterableUserDict?
I was writing some tests for a mapping class I have made, and I decided to run those same tests over dict and UserDict. The built-in dict passed all the tests, but UserDict failed one: class SimpleMappingTest(unittest.TestCase): type2test = UserDict.UserDict def test_iter(self): k, v = [0, 1, 2, 3], 'abcd' m = self.type2test(zip(k, v)) it = iter(m) self.assert_(iter(it) is it) self.assertEquals(sorted(it), k) # This line fails. # many more tests To cut a long story short, the problem is that UserDict doesn't support the modern iteration protocol. Python falls back on the old-fashioned __getitem__ iteration protocol, but since it expects IndexError rather than KeyError, iteration fails for UserDict once it hits key=4. If I look at the source code for the UserDict module, I discover that there's a second mapping class, IterableUserDict, specifically to make UserDict iterable. To do this requires a single one-line method: class IterableUserDict(UserDict): def __iter__(self): return iter(self.data) This class was apparently added to the module in 2.2 -- it doesn't exist in 2.1. Now that boggles my brain. Why was support for iteration added as a subclass, instead of simply adding the __iter__ method to UserDict? UserDict is supposed to be a drop-in replacement for dict (although the use-cases for it are much fewer now that we can inherit from dict), so it doesn't make sense to me to have a non-iterable UserDict plus a subclass which is iterable. Can anyone shed any light on this apparently bizarre design decision? -- Steven -- http://mail.python.org/mailman/listinfo/python-list

Using IFs is just plain ugly. Why not go for the much more pythonic
code = (lambda s:dir[slice(*(s*int(num),None)[::s])])(cmp('o',side))
Much easier on the eyes and no code duplication ... ;)

[OS X 10.5] hitting TAB inserts ./ in interactive mode ?
Hi all, Thanks for your help. I installed python 2.7 on my Mac OS X 10.5.8 machine: nik$ python Python 2.7 (r27:82508, Jul 3 2010, 21:12:11) [GCC 4.0.1 (Apple Inc. build 5493)] on darwin Type "help", "copyright", "credits" or "license" for more information. and now, when I hit TAB or paste in a code snippet with tabs in them, the interpreter tries to autocomplete a path, or inserts "./" if the line is blank (just as readline would in the shell environment). It does *not* try to autocomplete function (as readline would in python-- importing readline does turn on this functionality). And it does *not* insert a tab, as I would like it to! If i start my old python 2.5 which came with the OS, this is not a problem. I've tried setting a PYTHONIOENCODING, but that doesn't seem to be doing the job. Any ideas?

I ended up using Dispatch("WScript.Shell") and AppActivate("R

Hi Laszlo,
It's difficult to help without a complete working example. But I have a few
suggestions.
1) Why not call self.parent.Close()? It seems a bit more polite than .Destroy().
2) I saw this in the documentation for Destroy() -- "Frames and dialogs are not
destroyed immediately when this function is called -- they are added to a list
of windows to be deleted on idle time, when all the window's events have been
processed." That might be consistent with what you're seeing. The window you're
trying to destroy has no events in its queue. WHen you move the mouse over it,
the window processes those mouse events and then wx realizes, "Hey, this window
has processed all of its events, and it's on the list of windows to be
destroyed. I'd better get rid of it."
If you're interested in experimenting, find a non-mouse way to force that
window to process an event and I'll bet that would have the same effect as
moving the mouse over it.
3) Both the wxPython and wxWidgets mailing lists are probably better places to
ask for help on wxPython.
Good luck

I personally love them, they makes XML files looks more like python objects. foo bar being able to say: if a.b == 'foo': print a.c is very convenient.

So, personally I think both attribute-syntax and dict-syntax should continue; it should be up to the programmer to determine whether the limitations imposed by these syntaxes are suitable for their need (e.g. if the programmer knows he would only use alphabet tag name, then attr-style syntax is fine; and if he knows that there is no duplicate, then dict-style syntax is fine as well; and if he can't rely on both, then and only then, he'd be forced to do it the long way) -- http://mail.python.org/mailman/listinfo/python-list

self-closing window with wxPython
Hi,
I'd like to create a simple alarm application that shows an alarm
window. The application should shut down automatically after 5
seconds. The problem is the following:
* If I keep the mouse outside of the window, the application keeps
running. Somehow self.Destroy() is not taken into account.
* If the mouse is over the window and I keep moving it, the window closes.
I'm using Ubuntu Linux with wxPython 2.8. Below you can find what I have so far.
Thanks,
Laszlo

I recommend that you always list the column names explicitly to be on

Compiling SWIG Extensions With VC2008 and VC2010 Both Installed
I am attempting to compile a SWIG extension library for QuantLib (www.quantlib.org) on Windows 7 running Python 2.6. 2.6 needs VC2008 to compile extensions yet distutils cannot find this version, is there a way I can specify that this version be used?

Re: program organization question for web development with python
Hans a écrit : (snip) Maybe I did not make my question clear. I never tried python web programing before, so I want to start from CGI. You can indeed learn quite a few things doing raw CGI - the most important one being why frameworks are a good idea !-) I read something about web framework like django, but seems it's a little bit complicated. Not that much IMHO, but being an early django user I'm probably a bit biased. Now Python is known as "the language with more web frameworks than keywords", so you could probably check some lighter framework like web.py (http://webpy.org/) or flask (http://flask.pocoo.org/). my task is actually very simple: get search string from input, and then search database, print search result. I thought CGI should be good enough to do this. CGI is "good enough" to do any web stuff - just like assembler is "good enough" to write any application !-) I don't have any idea about how to organize those cgi codes, so what I'm asking is: 1. do I have to have each single file for each hyper-link? Can I put them together? how? > 2. how can I pass a db_cursor to another file? can I use db_cursor as a parameter? Obviously not. FWIW, both questions show a lack of understanding of the HTTP protocol, and you can't hope to do anything good in web programming if you don't understand at least the basics of the HTTP protocol, specially the request/response cycle. Now for a couple more practical answers: There are basically two ways to organize your url => code mapping: 1/ have only one cgi script and use querystring params to tell which action should be executed. 2/ have one cgi script per action. The choice is up to you. For a simple app like yours, the first solution is probably the most obvious : always display the seach form, if the user submitted the form also display the result list. That's how google works (wrt/ user interface I mean). Now if you still need / want to have distinct scripts and want to factor out some common code, you just put the common code in a module that you import from each script. -- http://mail.python.org/mailman/listinfo/python-list

I put together some code, which works as expected, but I suspect
somehow, that there must be better ways of doing it.
Two things I am not quite clear about are using the placeholders for
the data identifiers and "chaining" the SELECT parameters.
I Couldn't find a way to use "?" placeholder for table or column
names, hence I ended up using string interpolation for them and
placeholders for the data values, like.
curs.execute('SELECT * FROM "%s" WHERE "%s"==?' % (text_name,
index_col), (text_index,))
is there a better way or is it not supposed to supply these
identifiers programatically?
>>> You would normally expect the structure of the database to be fixed and

>>>
For getting the matching text indices given the tags, tag_values
combination I ended up with a clumsy query:
combined_query_list = ['SELECT "%s" FROM "%s" WHERE "%s"==?' %
(index_col, text_name, tag) for tag in tags]
sql_query = " INTERSECT ".join(combined_query_list)
curs.execute(sql_query, tag_values)
which produces e.g.:
SELECT "ind" FROM "n" WHERE "KC"==? INTERSECT SELECT "ind" FROM "n"
WHERE "VN"==?
or alternatively:
select_begin = 'SELECT "%s" FROM "%s" WHERE ' % (index_col, text_name)
where_subquery = " AND ".join('"%s"==?' % (tag,) for tag in tags)
sql_query = select_begin + where_subquery
with the resulting query string like:
SELECT "ind" FROM "n" WHERE "KC"==? AND "VN"==? ('12', '1')
(BTW, are these queries equivalent, as the outputs suggest, or are
there some distinctions to be aware of?)

Ok, thanks for confirming my suspicion :-),
Now I have to decide whether I shall use my custom data structure,
where I am on my own, or whether using an sql database in such a
non-standard way has some advantages...
The main problem indeed seems to be the fact, that I consider the
tagged texts to be the primary storage format, whereas the database is
only means for accessing it more conveniently.
Thanks again,

SimpleHTTPServer, external CSS, and Google Chrome
I am running "python -m SimpleHTTPServer 80" on Windows XP Pro SP 3
(Python 2.5.4)
browsing http://localhost/ using IE8 and FireFox 3.6, I get blue text
on red background
on Google Chrome 6.0 however, I get blue text on white background
placing index.htm and styles.css (see below) under IIS, I get blue
text on red background for all browsers,
including Google Chrome 6.0.
I get exactly the same results when browsing from another machine.
what's wrong? what do I need to change in SimpleHTTPServer?
index.htm
