I'm using python feedparser in an aggregator client that runs behind a squid proxy. I want it to send a cache-control: max-age=600 header in the request, so that we get a reasonably up-to-date response. (At the moment the feeds are returned by the proxy from its cache, even days after they changed, which is reasonable based on heuristi...
I'm using matplotlib to generate many plots of the results of a numerical simulation. The plots are used as frames in a video, and so I'm generating many of them by repeatedly calling a function similar to this one: from pylab import * def plot_density(filename,i,t,psi_Na): figure(figsize=(8,6)) imshow(abs(psi_Na)**2,origin =...
Somewhat related to my earlier question. I'm making a simple html parser to play around with in Python 2.7. I would like to have multiple parse types, IE can parse for links, script tags, images, ect. I'm using the HTMLParser module, so my initial thoughts were just make a separate class for each thing I want to parse. But that seemed ra...
I'm using pylons, and some of my urls contains non-English characters, such as: http://localhost:5000/article/111/文章标题 At most cases, it won't be a problem, but in my login module, after a user has logging out, I try to get the referer from the request.headers, and redirect to that url. if user_logout: referer = request.headers.g...
I have a simple form that submits a image to the blobstore and a title for the image. This works on my local devserver but when I deploy my code, non ascii letters in the title become garbled with some kind of mixture of ascii and hex. For example Ísland becomes =CDsland. Note, I am using <meta http-equiv="Content-Type" content="text/...
Obs: I know lists in python are not order-fixed, but think that this one will be. And I'm using Python 2.4 I have a list, like (for example) this one: mylist = [ ( u'Article', {"...some_data..."} ) , ( u'Report' , {"...some_data..."} ) , ( u'Book' , {"...another_data..."} ) , ...#continue ] This variable...

Suppose I have a namedtuple like this: EdgeBase = namedtuple("EdgeBase", "left, right") I want to implement a custom hash-function for this, so I create the following subclass: class Edge(EdgeBase): def __hash__(self): return hash(self.left) * hash(self.right) Since the object is immutable, I want the hash-value to be c...

Hi, I am trying to create a Maya to Maya interface using Python so I could possibly make a game from within Maya that runs on two different computer. I have successfully written ways to send commands from one Maya to another using the command "commandPort." The problem is when I start sending commands from another computer, it fails.I g...
Given a list of ids/pks, I'd like to generate a QuerySet of objects ordered by the index in the list. Normally I'd begin with: pk_list = [5, 9, 2, 14] queryset = MyModel.objects.filter(pk__in=pk_list) This of course returns the objects, but in the order of the models meta ordering property, and I wish to get the records in the order ...

socket.getfqdn() works fine with IPv4 addresses, for example: >>> import socket >>> socket.getfqdn("8.8.8.8") 'google-public-dns-a.google.com' However, it doesn't work for IPv6 addresses. >>> socket.getfqdn("2404:6800:8004::68") '2404:6800:8004::68' >>> socket.has_ipv6 True How can I do this with IPv6? Ideally with only modules in...

A common task I have to perform is an SQL-like JOIN on two text files. i.e. create a new file from the "left hand" and "right hand" files, using some sort of join on an identifier column shared between them. Variations such as outer joins etc are sometimes required. Of course I could write a simple script to do this in a generic way, b...
