I'm reading up on BeautifulSoup to screen-scrape some pretty heavy html pages. Going through the documentation of BeautifulSoup I can't seem to find a easy way to select child elements. Given the html: <div id="top"> <div>Content</div> <div> <div>Content I Want</div> </div> </div> I want a easy way to to get the "Content I ...
Is there a .NET/Python library that supports Bluetooth passkey authentication? I'd like to create a Windows desktop application that would scan for Bluetooth devices and interact with them. So in case of .NET it is .NET Desktop. What .NET/Python lib should I use (preferably the one that supports passkey authentication along with a no-a...
Hi Guys, I see a variation in output between C and python code in Windows trying to get the same functionality. The c code ( similar to unix shell scripts ) shows the TEST1 environment variable in 'test.bat.output' with its value as empty string whereas the python code removes this environment variable. Is there a way to ask Python ...
hello, how can I automate finding the pagerank of a domain? I came across this Python script but it no longer works. Seems Google doesn't like people automating this. So, is there an alternative provider of page rank scores? I do not need the exact same result as Google, but something comparable. ...
Put simply, is there a way to get generic views to work? If I try the following in urls.py: publisher_info = { 'queryset': Publisher.objects.all(), } urlpatterns = patterns('', (r'^publishers/$', list_detail.object_list, publisher_info) ) I get the following error: AttributeError at /publishers 'Query' object has no a...
Until recently users of my site were able to import data from Google, via OAuth. However, recently they have received the warning below, in a yellow box, when authorising (although the import still works). I've also noticed this same warning on Facebook's GMail authenticator! What's changed / am I missing? This website is registere...
I'm writing a ZenPack for Zenoss which includes a new DataSource. The DataSource has a ToOne relationship with another persistent object and I'm trying to construct the user interface to allow a user to specify the value of this relationship. I've given the DataSource a factory_type_information attribute with an "immediate_view" key ma...
def solve(numLegs, numHeads): for numSpiders in range(0, numHeads + 1): for numChicks in range(0, numHeads - numSpiders + 1): numPigs = numHeads - numChicks - numSpiders totLegs = 4*numPigs + 2*numChicks + 6*numSpiders if totLegs == numLegs: return [numPigs, numChicks, numSpid...
I am probably looking for the wrong thing in the handbook, but I am looking to take an image object and expand it without resizing (stretching/squishing) the original image. Toy example: imagine a blue rectangle, 200 x 100, then I perform some operation and I have a new image object, 400 x 300, consisting of a white background upon wh...
What's the shortest way to import a module from a distant, relative directory? We've been using this code which isn't too bad except your current working directory has to be the same as the directory as this code's or the relative path breaks, which can be error prone and confusing to users. import sys sys.path.append('../../../Path/To...
I'm refactoring some code and found this (simplified of course, but general idea): class Variable: def __init__(self): self.__constraints = [] def addConstraint(self, c): self.__constraints.append(c) class Constraint: def __init__(self, variables): for v in variables: v.addConstraint(sel...
I have an array in python that contains a set of values, some of them are 2.32313e+07 2.1155e+07 1.923e+07 11856 112.32 How do I convert the exponential formats to the decimal format Additional: Is there a way I can convert the exponent directly to decimal when printing out in UNIX with awk? ...
ZenPack development seems to involve the creation of a variety of persistent state. There are model classes which represent explicitly persistent state. There are skins which are associated with model objects. There are organizers and instances of persistent classes (data sources, graphs, etc). Considering that during development, ma...
I'm trying to develop a site that will allow users to pay for services with eChecks that other users are offering. The purchaser would pay money that would go into my account via direct deposit. The service provider could later withdraw money up to the amount they accumulated to their bank account. Every time I ask payment gateway prov...
I'm just learning python and confused when a "def" of a function ends? I see code samples like: def myfunc(a=4,b=6): sum = a + b return sum myfunc() I know it doesn't end because of the return (because I've seen if statements... if FOO than return BAR, else return FOOBAR). How does Python know this isn't a recursive functio...
I've been tackling this for a while. I setup a completely new machine. I've installed a fresh copy of postgresql and all my other dependencies. Basically, I get these database disconnections at random times. I can perform identical requests and either it works or it doesn't. Very nondeterministic in outward appearance. Watching logs at P...
I'm working with an output list that contains the following information: [start position, stop position, chromosome, [('sample name', 'sample value'), ('sample name','sample value')...]] [[59000, 59500, chr1, [('cn_04', '1.362352462'), ('cn_01', '1.802001235')]], [100000, 110000, chr1, [('cn_03', '1.88726...
I have a model and form like so: class Image(BaseModel): original = db.BlobProperty() class ImageForm(ModelForm): class Meta: model = Image I do the following in my view: form = ImageForm(request.POST, request.FILES, instance=image) if form.is_valid(): And I get: AttributeError at /image/add/ 'NoneType' object has...
Suppose I have many columns. If 2 columns match and are exactly the same, then they are duplicates. ID | title | link | size | author Suppose if link and size are similar for 2 rows or more, then those rows are duplicates. How do I get those duplicates into a list and process them? ...
I have an array of timestamps in the format (HH:MM:SS.mmmmmm) and another array of floating point numbers, each corresponding to a value in the timestamp array. Can I plot time on the x axis and the numbers on the y-axis using matplotlib? I was trying to but somehow it was only accepting arrays of floats.How can I get it to plot the tim...
