In Python compiled regex patterns have a findall method that does the following: Return all non-overlapping matches of pattern in string, as a list of strings. The string is scanned left-to-right, and matches are returned in the order found. If one or more groups are present in the pattern, return a list of groups; this ...
I have a list of objects (for the sake of example, let's say 5). I want a list of some of the possible permutations. Specifically, given that some pairs are not together, and some triples don't make sandwiches, how can I generate all other permutations? I realize that I generate all of them first and check that they work, but I think ...
I'm speaking of this module: http://docs.python.org/library/operator.html From the article: The operator module exports a set of functions implemented in C corresponding to the intrinsic operators of Python. For example, operator.add(x, y) is equivalent to the expression x+y. The function names are those used for special...
Hi. I'm used to sampling C-based apps, which every few milliseconds sees what function stack is being called at that moment. This allows me to see where most of the time is spent in an app so I can optimize it. When using python, however, sample isn't so helpful, since it's sampling the C functions of the python interpreter, not the py...
I have two models, Room and Image. Image is a generic model that can tack onto any other model. I want to give users a form to upload an image when they post information about a room. I've written code that works, but I'm afraid I've done it the hard way, and specifically in a way that violates DRY. Was hoping someone who's a little ...
A lot of modules I use import entire files into memory or trickle a file's contents in while they process it. I'm wondering if there's any way to track this sort of loading progress? Possibly a wrapper class that takes a callback? ...
I'm looking for a library, service, or code suggestions to turn spelled out numbers and amounts (eg. "thirty five dollars and fifteen cents", "one point five") into numerics ($35.15, 1.5) . Suggestions? ...
Hi. Python 2.5.1 http://www.cgsecurity.org/wiki/After_Using_PhotoRec I've just run PhotoRec and the code given as a way to sort file types into their own folder is coming back with this error. Any suggestions on how to alter? Thanks : [EDIT2: Two points: This question was voted down because it was a 'usage' of code, somehow not a p...
In Python we can "dir" a module, like this: >>> import re >>> dir(re) And it lists all functions in the module. Is there a similar way to do this in Ruby? ...

Are there any standalone type conversion libraries? I have a data storage system that only understands bytes/strings, but I can tag metadata such as the type to be converted to. I could hack up some naive system of type converters, as every other application has done before me, or I could hopefully use a standalone library, except I ca...
I've got a CMS that takes some dynamic content and renders it using a standard template. However I am now using template tags in the dynamic content itself so I have to do a render_to_string and then pass the results of that as a context variable to render_to_response. This seems wasteful. What's a better way to do this? ...
In Django how can i return the total number of items (count) that are related to another model, e.g the way stackoverflow does a list of questions then on the side it shows the count on the answers related to that question. This is easy if i get the questionid, i can return all answers related to that question but when am displaying th...
I'm new to the MDX/OLAP and I'm wondering if there is any ORM similar like Django ORM for Python that would support OLAP. I'm a Python/Django developer and if there would be something that would have some level of integration with Django I would be much interested in learning more about it. ...

I have looked through hald but couldn't find a good example. ...

As the title suggests, I'm using Google App Engine and Django. I have quite a bit of identical code across my templates and would like to reduce this by including template files. So, in my main application directory I have the python handler file, the main template, and the template I want to include in my main template. I would have t...
