I'm trying to run cProfile.runctx() on each process in a multiprocessing pool, to get an idea of what the multiprocessing bottlenecks are in my source. Here is a simplified example of what I'm trying to do: from multiprocessing import Pool import cProfile def square(i): return i*i def square_wrapper(i): cProfile.runctx("result...

Now, in order to display the rich text back to the user, I am forced to use the "safe" filter in Django templates so that HTML rich text can be displayed on the browser. Suppose JavaScript is disabled on the user's browser, TinyMCE won't load and the user could pass <script...

Hi all, I would like to ask about some sources for developing applications with Python and Google App Engine. For example, some controls to generate automatically pages with the insert/update/delete of a database table, or any other useful resources are welcome. Thank you! ...
Hi all, i'm importing several parts of a Databasedump in text Format into MySQL, the problem is that before the interesting Data there is very much non-interesting stuff infront.

When it's about archiving and doc portability, it's all about PDF. I heard about DjVu somes years ago, and it seems to be now mature enough for serious usages. The benefits seems to be a small size format and a fast open / read experience. But I have absolutely no feedback on how good / bad it is in the real world : Is it technically ...
First of all, please excuse me for any incoherence in the tile of this question. It probably has some, but really don't know better. This question was raised in the context of controlling iTunes via COM from python. >>> itunes = win32com.client.Dispatch("iTunes.Application") >>> itunes <win32com.gen_py.iTunes 1.12 Type Library.IiTunes ...
On google appengine, you can retrieve the hash key value by doing a query like select __key__ from furniture But appengine datastore maintains a nicely autoincremented field ID for each kind. How can I access it from a query? select ID from furniture Doesn't work ...

However, StaticBitmap doesn't emit EVT_WINDOW_ENTER, EVT_WINDOW_LEAVE events. I can work with EVT_MOTION. If images are switched when the c...
I come from a background in static languages. Can someone explain (hopefully through example) the real world advantages of using **kwargs over named arguments? To me it they seem to only make the function call more ambiguous. Thanks. ...
I have some code like this one: >>> import re >>> p = re.compile('my pattern') >>> print p _sre.SRE_Pattern object at 0x02274380 Is it possible to get string "my pattern" from p variable? ...
Seems everyone recommends virtualenv for multiple python versions (on osx), but does it even work with python 3.0? I downloaded it, and it doesn't seem to.. And I don't really understand how it works, Can you 'turn on' on env at a time or something? What I want is to leave the system python 2.5 (obviously), and to have python 3.1.1 with ...
I know that this is a difficult question to answer, but I thought I would try anwyays.... I am just starting at a new company where they have a minimal existing code base. It probably has a month of man effort invested at this point. It is currently written in Ruby. It is also currently using Ruby on Rails -- but mostly just for the...
I have a function whose input argument can either be an element or a list of elements. If this argument is a single element then I put it in a list so I can iterate over the input in a consistent manner. Currently I have this: def my_func(input): if not isinstance(input, list): input = [input] for e in input: ... I a...
Hi! In python-mode, there is a function called py-execute-region which sends a highlighted region of code to the Python buffer for evaluation. After evaluation, the cursor is in the Python buffer, but I would prefer that it remain in the script buffer so I can continue producing more code. I wrote a simple advising function: (defadvice ...
I'm using google appengine (python, of course :) ) and I'd like to do a string.replace on a string from the template file. {% for item in items %} <p>{{ item.code.replace( '_', ' ' ) }}</p> {% endfor %} But that isn't working. So we cannot execute anything other than basic checks in the app engine templates. Is that Correct ? ...
I'm trying to call a function in a Python script from my main C++ program. The python function takes a string as the argument and returns nothing (ok.. 'None'). It works perfectly well (never thought it would be that easy..) as long as the previous call is finished before the function is called again, otherwise there is an access violat...
Can anyone share an efficient code snipper to daemonize a process in python? ...
Background Python has "textwrap" and "dedent" functions. They do pretty much what you expect to any string you supply. textwrap.wrap(text[, width[, ...]]) Wraps the single paragraph in text (a string) so every line is at most width characters long. Returns a list of output lines, without final newlines. textwrap.dedent(tex...
I want to unify the whole logging facility of my app. Any warning is raise an exception, next I catch it and pass it to the logger. But the question: Is there in logging any mute facility? Sometimes logger becomes too verbose. Sometimes for the reason of too noisy warnings, is there are any verbose limit in warnings? http://docs.python....
