  • How to optimize this Python code?

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

  • jQuery and PHP suggested answers

    - by Samir Ghobril
    Hey guys, there is a form where the user select some of his friends and I'm curious on how I can implement a list that searches simultaneously while the user is typing a friend's name and when he selects the name the name is written in the text box(jQuery). And if the user wants to select more than one friend, when I'm inserting the names in the database, how can I separate the names that are written in one input field?

  • Oracle: Is there a way to get the column data types for a view?

    - by rally25rs
    For a table in oracle, I can query "all_tab_columns" and get table column information, like the data type, precision, whether or not the column is nullable. In SQL Developer or TOAD, you can click on a view in the GUI and it will spit out a list of the columns that the view returns and the same set of data (data type, precision, nullable, etc). So my question is, is there a way to query this column definition for a view, the way you can for a table? How do the GUI tools do it?

  • How Android BaseAdapter notifyDataSetChanged works?

    - by Yama moto
    In the document for the method notifyDataSetChanged of class BaseAdapter noted that "Notifies the attached observers that the underlying data has been changed and any View reflecting the data set should refresh itself.

Does the 3rd view item in my list view be notified ? Also, how is notifyDataSetChanged() and getView() concerned ? Thanks in advance

  • A more elegant way to parse a string with ruby regular expression using variable grouping?

    - by i0n
    At the moment I have a regular expression that looks like this: ^(cat|dog|bird){1}(cat|dog|bird)?(cat|dog|bird)?$ It matches at least 1, and at most 3 instances of a long list of words and makes the matching words for each group available via the corresponding variable. Is there a way to revise this so that I can return the result for each word in the string without specifying the number of groups beforehand? ^(cat|dog|bird)+$ works but only returns the last match separately , because there is only one group.

  • COM library for Explorer-like system views

    - by chrisd
    To provide a Windows Explorer-like view of the user's system, we have been using the shell controls from LogicNP (formerly Sky Software), but these have deficiencies, e.g., no support for Win7 libraries. The vendor has not responded to our inquiries about updates, so we're looking to replace the package. Requirements: ActiveX (no managed code or MFC) Tree and list views of the system Per-item checkboxes 32- and 64-bit versions Any recommendations for a replacement product? TIA.

  • How to perform gui operation in doInBackground method?

    - by jM2.me
    My application reads a user selected file which contains addresses and then displays on mapview when done geocoding. To avoid hanging app the importing and geocoding is done in AsyncTask. public class LoadOverlayAsync extends AsyncTask<Uri, Integer, StopsOverlay> { Context context; MapView mapView; Drawable drawable; public LoadOverlayAsync(Context con, MapView mv, Drawable dw) { context = con; mapView = mv; drawable = dw; } protected StopsOverlay doInBackground(Uri... uris) { StringBuilder text = new StringBuilder(); StopsOverlay stopsOverlay = new StopsOverlay(drawable, context); Geocoder geo = new Geocoder(context, Locale.US); try { File file = new File(new URI(uris[0].toString())); BufferedReader br = new BufferedReader(new FileReader(file)); String line; while ((line = br.readLine()) != null) { StopOverlay stopOverlay = null; String[] tempLine = line.split("~"); List<Address> results = geo.getFromLocationName(tempLine[4] + " " + tempLine[5] + " " + tempLine[7] + " " + tempLine[8], 10); if (results.size() > 0) { Toast progressToast = Toast.makeText(context, "More than one yo", 1000); progressToast.show(); } else if (results.size() == 1) { Address addr = results.get(0); GeoPoint mPoint = new GeoPoint((int)(addr.getLatitude() * 1E6), (int)(addr.getLongitude() * 1E6)); stopOverlay = new StopOverlay(mPoint, tempLine); } if (stopOverlay != null) { stopsOverlay.addOverlay(stopOverlay); } //List<Address> results = geo.getFromLocationName(locationName, maxResults) } } catch (URISyntaxException e) { showErrorToast(e.toString()); //e.printStackTrace(); } catch (FileNotFoundException e) { showErrorToast(e.toString()); //e.printStackTrace(); } catch (IOException e) { showErrorToast(e.toString()); //e.printStackTrace(); } return stopsOverlay; } protected void onProgressUpdate(Integer... progress) { Toast progressToast = Toast.makeText(context, "Loaded " + progress.toString(), 1000); progressToast.show(); } protected void onPostExecute(StopsOverlay so) { //mapView.getOverlays().add(so); Toast progressToast = Toast.makeText(context, "Done geocoding", 1000); progressToast.show(); } protected void showErrorToast(String msg) { Toast Newtoast = Toast.makeText(context, msg, 10000); Newtoast.show(); } } But if geocode fails, I want a dialog popup to let user edit the address. That would require calling on gui method while in doInBackground. What would be a good workaround this?

    I have the following model: class Service(models.Model): ratings = models.ManyToManyField(User) Now if I wanna get all the service with ratings sorted in descending order I did something: services_list = Service.objects.filter(ratings__gt=0).distinct() services_list = list(services_list) services_list.sort(key=lambda service: service.ratings.all().count(), reverse=True) As you can see its a three step process and I don't feel right about this. Anybody who knows a better way to do this?

  • Dynamically loading modules in Python (+ threading question)

    - by morpheous
    I am writing a Python package which reads the list of modules (along with ancillary data) from a configuration file. I then want to iterate through each of the dynamically loaded modules and invoke a do_work() function in it which will spawn a new thread, so that the code runs in a separate thread. At the moment, I am importing the list of all known modules at the beginning of my main script - this is a nasty hack I feel, and is not very flexible, as well as being a maintenance pain. This is the function that spawns the threads. I will like to modify it to dynamically load the module when it is encountered. The key in the dictionary is the name of the module containing the code: def do_work(work_info): for (worker, dataset) in work_info.items(): #import the module defined by variable worker here... t = threading.Thread(target=worker.do_work, args=[dataset]) # I'll NOT dameonize since spawned children need to clean up on shutdown # Since the threads will be holding resources #t.daemon = True t.start() Question 1 When I call the function in my script (as written above), I get the following error: AttributeError: 'str' object has no attribute 'do_work' Which makes sense, since the dictionary key is a string (name of the module to be imported). When I add the statement: import worker before spawning the thread, I get the error: ImportError: No module named worker This is strange, since the variable name rather than the value it holds are being used - when I print the variable, I get the value (as I expect) whats going on? Question 2 As I mentioned in the comments section, I realize that the do_work() function written in the spawned children needs to cleanup after itself. My understanding is to write a clean_up function that is called when do_work() has completed successfully, or an unhandled exception is caught - is there anything more I need to do to ensure resources don't leak or leave the OS in an unstable state? Question 3 If I comment out the t.daemon flag statement, will the code stil run ASYNCHRONOUSLY?. The work carried out by the spawned children are pretty intensive, and I don't want to have to be waiting for one child to finish before spawning another child. BTW, I am aware that threading in Python is in reality, a kind of time sharing/slicing - thats ok Lastly is there a better (more Pythonic) way of doing what I'm trying to do?

  • Android Assets No Value Read?

    - by BahaiResearch.com
    AssetManager assets = myContext.getAssets(); String[] files = assets.list("MyFolder"); InputStream myInput = assets.open("MyFolder/" + files[0]); int i = myInput.read(); in this case 'i' is -1 meaning nothing read. Why would nothing be there if the file is there, the variable 'files' has the file as well. Do I need to do anything to the file I put into the Assets folder in get it to be readable?
