  • python: how to convert list of lists into a single nested list

    - by Bhuski
    I have a python list of lists as shown below: mylist=[ [['orphan1', ['some value1']]], [['parent1', ['child1', ['child', ['some value2']]]]], [['parent1', ['child2', ['child', ['some value3']]]]] ] I need to convert the above list to some thing like this: result=[ ['orphan1', ['some value1']], ['parent1', ['child1', ['child', ['some value2']]], ['child2', ['child', ['some value3']]]] ] Kindly help me approach this problem. I have given only simple list. In actual scenario here, in my list, even grand parents/grand childs are there. How much ever deep the input nested list is, I need to convert it to a single nested list, with common list elements (parents and grand parents) appearing only once. (but the next to innermost list element('child' in above example) should appear as many times it occurs in the input list. I have been trying to do this last two days, but did not end up with working solution :(. I need to use the output in django template filter: unordered_list so that the resultant nested list appears as a nested unordered list in my html page ..

  • Converting mp3 to ogg, suggestive?

    - by watain
    I'm thinking about converting my mp3 based music library to ogg, due to ogg being a free and open standard format (I guess there are other reasons too). As far as I know there's a chance of losing some sound quality when converting mp3 to ogg and vice versa (?). Would you suggest converting mp3 to ogg, or is it such a bad idea that I'd have to rip all CDs to ogg instead of converting? (if this would turn up I'd rip to flac anyway I guess). How would I be able to convert mp3 to ogg the easiest way, copying ID3-Tags too? (on a *nix-based environment) Best regards!

  • Python utf-8 decoding issue with hashlib.digest() method

    - by Sorw
    Hello StackOverflow community, Using Google App Engine, I wrote a keyToSha256() method within a model class (extending db.Model) : class Car(db.Model): def keyToSha256(self): keyhash = hashlib.sha256(str(self.key())).digest() return keyhash When displaying the output (ultimately within a Django template), I get garbled text, for example : ?????_??!`?I?!?;?QeqN??Al?'2 I was expecting something more in line with this : 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 Am I missing something important ? Despite reading several guides on ASCII, Unicode, utf-8 and the like, I think I'm still far from mastering the secrets of string encoding/decoding. After browsing StackOverflow and searching for insights via Google, I figured out I should ask the question here. Any idea ? Thanks !

  • Help with Linq Expression - INotifyPropertyChanged

    - by Stephen Patten
    Hello, I'm reading the source code from the latest Prism 4 drop and am interested in solving this problem. There is a base class for the ViewModels that implements INotifyPropertyChanged and INotifyDataErrorInfo and provides some refactoring friendly change notification. protected void RaisePropertyChanged<T>(Expression<Func<T>> propertyExpresssion) { var propertyName = ExtractPropertyName(propertyExpresssion); this.RaisePropertyChanged(propertyName); } private string ExtractPropertyName<T>(Expression<Func<T>> propertyExpresssion) { if (propertyExpresssion == null) { throw new ArgumentNullException("propertyExpression"); } var memberExpression = propertyExpresssion.Body as MemberExpression; if (memberExpression == null) { throw new ArgumentException("The expression is not a member access expression.", "propertyExpression"); } var property = memberExpression.Member as PropertyInfo; if (property == null) { throw new ArgumentException("The member access expression does not access property.","propertyExpression"); } if (!property.DeclaringType.IsAssignableFrom(this.GetType())) { throw new ArgumentException("The referenced property belongs to a different type.", "propertyExpression"); } var getMethod = property.GetGetMethod(true); if (getMethod == null) { // this shouldn't happen - the expression would reject the property before reaching this far throw new ArgumentException("The referenced property does not have a get method.", "propertyExpression"); } if (getMethod.IsStatic) { throw new ArgumentException("The referenced property is a static property.", "propertyExpression"); } return memberExpression.Member.Name; } and as an example of it's usage private void RetrieveNewQuestionnaire() { this.Questions.Clear(); var template = this.questionnaireService.GetQuestionnaireTemplate(); this.questionnaire = new Questionnaire(template); foreach (var question in this.questionnaire.Questions) { this.Questions.Add(this.CreateQuestionViewModel(question)); } this.RaisePropertyChanged(() => this.Name); this.RaisePropertyChanged(() => this.UnansweredQuestions); this.RaisePropertyChanged(() => this.TotalQuestions); this.RaisePropertyChanged(() => this.CanSubmit); } My question is this. What would it take to pass an array of the property names to an overloaded method (RaisePropertyChanged) and condense this last bit of code from 4 lines to 1? Thank you, Stephen

  • How does the iPhone know which OpenGL ES context to use between 1.1 and 2.0?

    - by Moshe
    I've been digging around the net recently and noticed some video tutorials show an older template (pre SDK 3.2) with one OpenGL ES context. Now there are two of them, which, I've gleaned are the two versions of OpenGL ES available on the newer iMobile devices. Can I just use the older one or do I need to do everything twice? How do I tell the iPhone to use the older context, or will it do so automatically?

  • Geodjango: importing data from OSGB_1936, displaying in WGS84?

    - by AP257
    I have some polygon data saved in a PostGIS database with projection SRID 27700. geom = models.MultiPolygonField(srid=27700) I want to display the shapes on OpenStreetMap, i.e. with SRID 900913 (I think?). So, two questions: How do I change the code below to output with the right SRID for OpenStreetMap? How can I change the Django code below to give me a nice json object, ready to display as a polygon? area = get_object_or_404(soa.objects, code=my_code) polygon = area.geom return render_to_response('area.html', { 'area': area }, context_instance = RequestContext(request)) Apologies if this question doesn't make sense - I'm pretty new to GeoDjango.

    Given a [mysql] database with a given schema, is it possible to generate an ORM interface for it? doesn't matter if its php, python or perl. in other words, I have a database and I have to ask it a few questions. while I could just craft a bunch of SQL queries (okay, several dozen), this is way more interesting to think about. is this a valid question, even? I have no design background with ORMs, but I've used a few (django's, symfony's, etc).

  • How can I stop sorl thumbnail from breaking with very long filenames?

    - by bitbutter
    I've noticed that when working with SORL thumbnail, sometimes a user will upload an image with a very long filename, longer than the varfield in the database can hold. The name gets truncated in the database and the project gives errors whenever the image is requested. Is there a smart and safe way to have django automatically truncate long filenames in sorl uploads (prior to saving them in the database) to prevent this sort of thing? As reference, here's how the relevant model from my current project looks: class ArtistImage(models.Model): artist = models.ForeignKey(Artist) position = models.IntegerField() image = ThumbnailField( thumbnail_tag='<span class="artistimagewrapper"><img class="artistimage" src="%(src)s" width="%(width)s" height="%(height)s"></span>', upload_to='uploaded_images/artistimages', size=(900,900), quality=100, options={'crop': 'center'}, extra_thumbnails={ 'small':{ 'size':(92,92), 'quality':100, 'options':{'crop': 'center'}, } } ) class Meta: ordering = ('image',) def __unicode__(self): return (u"%s" % self.image)

  • Getting-started: Setup Database for Node.js

    - by Emile Petrone
    I am new to node.js but am excited to try it out. I am using Express as a web framework, and Jade as a template engine. Both were easy to get setup following this tutorial from Node Camp. However the one problem I am finding is I can't find a simple tutorial for getting a DB set up. I am trying to build a basic chat application (store session and message). Does anyone know of a good tutorial? This other SO post talks about dbs to use- but as this is very different from the Django/MySQL world I've been in, I want to make sure I understand what is going on. Thanks!
