I've just started playing with Django and am loosely following the tutorial with my own set of basic requirements. The models I've sketched out so far are a lot more comprehensive than the tutorial, but they compile fine. Otherwise, everything should have been the same. My problem is with the admin application. I can log into it, and vi...

I need to find all occurrences of a function call in a c++ file using python, and extract the arguments for each call. I'm playing with the pygccxml package, and extracting the arguments given a string with the function call is extremely easy: from pygccxml.declarations import call_invocation def test_is_call_invocation(call): if c...
I have built the IronPythonIntegration solution that comes with the Visual Studio 2005 SDK (as explained at http://www.izume.com/2007/10/13/integrating-ironpython-with-visual-studio-2005), and I can now use IronPython projects inside Visual Studio 2005. However, to let a Python file import from the standard library I need to include thes...
I once did a cursory search and found no good CVS bindings for Python. I wanted to be able to write helper scripts to do some fine-grained manipulation of the repository and projects in it. I had to resort to using popen and checking the stdout and stderr and then parsing those. It was messy and error-prone. Are there any good qualit...
I am looking for a script to allow users to add a text field to a .dbf table(e.g. landuse categories) and allow them to input/update the rows basing on what values in the GRIDCODE (numeric categories) field they think should be assigned into text categories.i.e. if GRIDCODE value is 4, the corresponding field value of landuse/landclass ...
I don't care what the differences are. I just want to know whether the contents are different. ...
I plan to use PyInstaller to create a stand-alone python executable. PythonInstaller comes with built-in support for UPX and uses it to compress the executable but they are still really huge (about 2,7 mb). Is there any way to create even smaller Python executables? For example using a shrinked python.dll or something similiar? ...

How do I convert a datetime or date object into a POSIX timestamp in python? There are methods to create a datetime object out of a timestamp, but I don't seem to find any obvious ways to do the operation the opposite way. ...
In python, if I say print 'h' I get the letter h and a newline. If I say print 'h', I get the letter h and no newline. If I say print 'h', print 'm', I get the letter h, a space, and the letter m. How can I prevent Python from printing the space? The print statements are different iterations of the same loop so I can't just...
In the context of a Google App Engine Webapp framework application: I want to changed the request verb of a request in the case a parameter _method is provided, for example if a POST request comes in with a parameter _method=PUT, I need to change the request to call the put method of the handler. This is to cope with the way prototype.j...
I've currently skimming through the Python-bindings for Redland and haven't found a clean way to do transactions on the storage engine via it. I found some model-transactions within the low-level Redland module: import RDF, Redland storage = RDF.Storage(...) model = RDF.Model(storage) Redland.librdf_model_transaction_start(model._model...
I kind of wish that there were a version of re.findall that returned groupdicts instead of just groups. Am I missing some simple way to accomplish the same result? (Does anybody know of a reason that this function doesn't exist?) ...
I would like to know if it is possible to determine if a function parameter with a default value was passed in Python. For example, how does dict.pop work? >>> {}.pop('test') Traceback (most recent call last): File "<stdin>", line 1, in <module> KeyError: 'pop(): dictionary is empty' >>> {}.pop('test',None) >>> {}.pop('test',3) 3 >>> ...
I'm sure this has been asked before, but I can't find it. What are the benefits/limitations of using a browser-based interface for a stand-alone application vs. using a normal GUI framework? I'm working on a Python program currently implement with wxPython for the GUI. The application is simply user-entry forms and dialogs. I am consi...

Example: User is typing as URL: http://www.sta Suggestions which would be displayed: http://www.staples.com http:...
I have written a script that goes through a bunch of files and snips out a portion of the files for further processing. The script creates a new directory and creates new files for each snip that is taken out. I have to now evaluate each of the files that were created to see if it is what I needed. The script also creates an html index...
I was wondering about the best practices for indicating invalid argument combinations in Python. I've come across a few situations where you have a function like so: def import_to_orm(name, save=False, recurse=False): """ :param name: Name of some external entity to import. :param save: Save the ORM object before returning. ...
