  • json KeyError with json.loads

    - by user322775
    my apologies in advance for a python and json nubie question. json seems to be hiccuping on the following statements: {"delete":{"status":{"id":12600579001,"user_id":55389449}}} code snippet: temp = json.loads(line) text = temp['text'] I get the following error output when the above code snippet encounters lines similar to the above json 'dictionary': text = temp['text'] KeyError: 'text' Is it because there is no "text" key in the line or because "delete" is not in the dictionary?

  • How to extend/patch an existing module or package?

    - by nat
    I want to extend some locale-specific features of a python application named OpenERP. All I need is implementing a third party module.function that would be called every time OpenERP calls locale.setlocale() function without changing neither OpenERP nor locale module source code. The only way I can imagine is provide a module named locale.py inside main application package dir, but It seems that is an unpythonic workaround.

  • GAE modeling relationship options

    - by Sway
    Hi there, I need to model the following situation and I can't seem to find a consistent example on how to do it "correctly" for the google app engine. Suppose I've got a simple situation like the following: [Company] 1 ----- M [Stare] A company has one to many stores. Each store has an address made up of a address line 1, city, state, country, postcode etc. Ok. Lets say we need to create say an "Audit". An Audit is for a company and can be across one to many stares. So something like: [Audit] 1 ------ 1 [Company] 1 ------ M [Store] Now we need to query all of the "audits" based on the Store "addresses" in order to send the "Auditors" to the right locations. There seem to be numerous articles like this one: http://code.google.com/appengine/articles/modeling.html Which give examples of creating a "ContactCompany" model class. However they also say that you should use this kind of relationship only when you "really need to" and with "care" for performance. I've also read - frequently - that you should denormalize as much as possible thereby moving all of the "query-able" data into the Audit class. So what would you suggest as the best way to solve this? I've seen that there is an Expando class but I'm not sure if that is the "best" option for this. Any help or thoughts on this would be totally appreciated. Thanks in advance, Matt

  • Checkers board structure

    - by Ockonal
    Hello guys, I'm implement checkers (game) board with python. Here is how I switch it to the need structure [8][8] array: _matrix = [] for i in xrange(8): _matrix.append( [' '] * 8 ) for row in xrange(0, 8): for col in xrange(0, 8): if _darkQuad(row, col) == True: _matrix[row][col] = '#' else: _matrix[row][col] = '-' def _darkQuad(row, col): return ((row%2) == (col%2)) def _printDebugBoard(): for row in xrange(0, 8): for col in xrange(0, 8): print _matrix[row][col] print '' This should do my board like: # - # - # - # - - # - # - # - # ... But the result is: - - - - - - - - # # # # # # # # - - - - - - - - # # # # # # # # - - - - - - - - # # # # # # # # - - - - - - - - # # # # # # # # What's wrong?

  • struct.error: unpack requires a string argument of length 4

    - by Thomas O
    Python says I need 4 bytes for a format code of "BH": struct.error: unpack requires a string argument of length 4 Here is the code, I am putting in 3 bytes as I think is needed: major, minor = struct.unpack("BH", self.fp.read(3)) "B" = Unsigned char (1 byte) + "H" unsigned short (2 bytes) = 3 bytes (!?) struct.calcsize("BH") says 4 bytes.

  • Calling activateWindow on QDialog sends window to background

    - by Stan
    I am debugging certain application written with C++/Qt4. On Linux it has problems that with certain window managers (gnome-wm/metacity), the main window (based on QDialog) is created in the background (it's not raised). I managed to re-create the scenario using PyQt4 and following code: from PyQt4.QtCore import * from PyQt4.QtGui import * import sys class PinDialog(QDialog): def showEvent(self, event): QDialog.showEvent(self, event) self.raise_() self.activateWindow() if __name__ == "__main__": app = QApplication(sys.argv) widget = PinDialog() app.setActiveWindow(widget) widget.exec_() sys.exit(0) If I remove self.activateWindow() the application works as expected. This seems wrong, since documentation for activateWindow does not specify any conditions under which something like this could happen. My question is: Is there any reason to have activateWindow in showEvent in the first place? If there is some reason, what would be good workaround for focusing issues?

  • Incorrect XML produced by SUDS

    - by Ben
    Hi, I am trying to talk to a SOAP web service using SUDS and Python. After lots of messing around learning Python (yes I am new to this) and working out how to use SUDS I have come across a problem. The signature of the web method I am calling, according to suds, is (FWTCaseCreate){ ClassificationEventCode = None Priority = None Title = None Description = None Queue = None DueDate = None AssociatedObject = (FWTObjectBriefDetails){ ObjectID = (FWTObjectID){ ObjectType = None ObjectReference[] = <empty> } ObjectDescription = None Details = None Category = None } Form = (FWTCaseForm){ FormField[] = <empty> FormName = None FormKey = None } Internal = None InteractionID = None XCoord = None YCoord = None } So I use SUDS to create the classes that I want and send it to the method. However I get an error. So I turned logging on and I can see that the XML that is being sent is not correct which is causing a deserialize error. The SOAP package looks like the following <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:ns0="http://www.lagan.com/wsdl/FLTypes" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header> <wsse:Security> <wsse:BinarySecurityToken>eaadf1ddff99a8</wsse:BinarySecurityToken> </wsse:Security> </SOAP-ENV:Header> <ns1:Body> <ns0:FWTCaseCreate> <ClassificationEventCode> <ClassificationEventCode>2000023</ClassificationEventCode> <Priority>1</Priority> <Title>testing</Title> <Description>testing</Description> <Queue/> <Internal>True</Internal> <XCoord>356570</XCoord> <YCoord>168708</YCoord> </ClassificationEventCode> </ns0:FWTCaseCreate> </ns1:Body> As you can see there is a 'ClassificationEventCode' element around all the other elements, this should not be there. If I cut and paste this xml into SOAPUI and first remove this element and then post it directly to the web service it works successfully. Does anyone have any ideas why this is happening? I guess SUDS thinks that it should be there based on the WSDL. Thanks.

  • Word XML to RTF conversion

    - by Chathuranga Chandrasekara
    I am in a need of programatically convert an Word-XML file into a RTF file. It has become a requirement, because of some third party libraries. Any API/Library that can do that? Actually the language is not a problem because I just need to work done. But Java, .NET languages or Python are preferred.

  • What are 'len', 'dir', 'vars' named?

    - by johannix
    I was wondering what language to use when talking about a function that takes in a specific object, acts on it and returns something else. Clearly they're functions, but I was wondering if there's a more specific term. A couple examples of Python built-in functions that fit this spec are: 'len', 'dir', 'vars' I thought it was 'predicate', but apparently that's specific to functions that return a boolean value.

  • parsing a string based on specified identifiers

    - by jml
    Let's say that I have the following text: input = "one aaa and bbb two bbbb er ... // three cccc" I would like to parse this into a group of variables that contain criteria = ["one", "two", "three"] v1,v2,v3 = input.split(criteria) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml

  • changing .emacs to use IronPython.exe and using code completion for IronPython modules ?

    - by KaluSingh Gabbar
    I configured my Emacs for code completion and other help using this link (from another question here on SO). I am a complete newbie to emacs. Can anyone tell me what should I change so it (rope, ropemacs, pymacs, yasnippet etc) picks up symbols of IronPython modules for code completion and snippets. Also I want to map: C-x RET - to invoke IronPython.exe and not Python.exe (any clue on how to do that) PS I am using Emacs with Cygwin on XP machine

  • Android MediaPlayer crashing app

    - by user1555863
    I have an android app with a button that plays a sound. the code for playing the sound: if (mp != null) { mp.release(); } mp = MediaPlayer.create(this, R.raw.match); mp.start(); mp is a field in the activity: public class Game extends Activity implements OnClickListener { /** Called when the activity is first created. */ //variables: MediaPlayer mp; //... The app runs ok, but after clicking the button about 200 times on the emulator, app crashed and gave me this error https://dl.dropbox.com/u/5488790/error.txt (couldn't figure how to post it here so it will appear decently) i am assuming this is because the MediaPlayer object is consuming up too much memory, but isn't mp.release() supposed to take care of this? What am i doing wrong here?

  • Sorting a string in array, making it sparsely populated.

    - by S1syphus
    For example, say I have string like: duck duck duck duck goose goose goose dog And I want it to be as sparsely populated as possible, say in this case duck goose duck goose dog duck goose duck What sort of algorithm would you recommend? Snippets of code or general pointers would be useful, languages welcome Python, C++ and extra kudos if you have a way to do it in bash.

  • SparkViewEngine, RenderAction and Areas with ASP MVC 2 Beta?!

    - by scooby37
    I just ran into trouble with the AreaDescriptionFilter of Spark using MVC 2 Beta. The following line is from my Application.spark file. It results in the view engine looking in all possible locations of the view - except in the folders of the area "Shell". # Html.RenderAction("ShowMainMenu", "Navigation", new { area = "Shell" }); Running the same action using http://localhost/Shell/Navigation/ShowMainMenu executes fine and recognizes the area's view directory as expected. Any ideas how to fix this?

  • Command line semaphore utility

    - by compie
    I want to write a command line utility that can be used to synchronize the execution off programs in different consoles. Console A: $ first_program && semaphore -signal Console B: $ semaphore -wait && second_program The first program takes a long take to complete. The second program can only start when the first program has finished. Which synchronization object do I need to implement this (in Python)?
