  • different behavior when using re.finditer and re.match.

    - by Shahzad
    Hi, I'm working on a regex to to collect some values from a page through some script. I'm using re.match in condition but it returns false but if i use finditer it returns true and body of condition is executed. i tested that regex in my own built tester and it's working there but not in script. here is sample script. result = [] RE_Add0 = re.compile("\d{5}(?:(?:-| |)\d{4})?", re.IGNORECASE) each = ''Expiration Date:\n05/31/1996\nBusiness Address: 23901 CALABASAS ROAD #2000 CALABASAS, CA 91302\n' if RE_Add0.match(each): result0 = RE_Add0.match(each).group(0) print result0 if len(result0) < 100: result.append(result0) else: print 'Address ignore' else: None

  • jQueryUI dialog width

    - by user35295
    Fiddle Full Screen Example I use jQuery dialog to open tables. Some of them have a large amount of text and they tend to be too long and go way off the screen. How can I make the dialog wider if the table is too long like the first one in the fiddle? I've tried width:'auto' but it seems to just occupy the entire screen. HTML: <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> Javascript: $(document).ready(function(){ $('.label').each(function() { var dialogopen = $(this).next(".dialog"); dialogopen.dialog({width:'auto',autoOpen: false,modal: true, open: function(){ jQuery('.ui-widget-overlay').bind('click',function(){ dialogopen.dialog('close'); }) } }); $(this).click(function(){ dialogopen.dialog('open'); return false; } ); }); });

  • Issue using Python to solve the Coin problem [closed]

    - by challarao
    I'm attempting to solve a problem commonly known as the Coin problem, but using McNuggets. McNuggets come in boxes containing either 6, 9, or 20 nuggets. I want to write a python script that uses Diophantine equations to determine if a given number of McNuggets n can be exactly purchased in these groupings. For example: 26 McNuggets -- Possible: 1 6-pack, 0 9-packs, 1 20-pack 27 McNuggets -- Possible: 0 6-packs, 3 9-packs, 0 20-packs 28 McNuggets -- Not possible This is my current attempt at writing the solution in Python, but the output is incorrect and I'm not sure what's wrong. n=input("Enter the no.of McNuggets:") a,b,c=0,0,0 count=0 for a in range(n): if 6*a+9*b+20*c==n: count=count+1 break else: for b in range(n): if 6*a+9*b+20*c==n: count=count+1 break else: for c in range(n): if 6*a+9*b+20*c==n: count=count+1 break if count>0: print "It is possible to buy exactly",n,"packs of McNuggetss",a,b,c else: print "It is not possible to buy"

  • Hide header if node body is empty - Drupal php snippet help

    - by Toxid
    Hello! I've made a content type for links, I'm trying to make a link directory. People only have to submit the link, description is voluntary. If no description is entered, I want the header that says "description" to disappear. The description field is the node body. Right now my snippet looks like this <?php if (!empty($node->body)) {?> <div class="field field-type-link field-field-link-archive"> <h3>Description</h3> <?php print $node->content['body']['#value'] ?></div> <?php }?> I expect this to check if node body is not empty, and if it isn't it'll print what's there. The problem is that the Description header is still printed out even if the node body is empty. Can anyone see what's wrong?

  • Exception message (Python 2.6)

    - by TurboJupi
    If I want to open binary file (in Python 2.6), that doesn't exists, program exits with an error and prints this: Traceback (most recent call last): File "C:\Python_tests\Exception_Handling\src\exception_handling.py", line 4, in <module> pkl_file = open('monitor.dat', 'rb') IOError: [Errno 2] No such file or directory: 'monitor.dat' I can handle this with 'try-except', like: try: pkl_file = open('monitor.dat', 'rb') monitoring_pickle = pickle.load(pkl_file) pkl_file.close() except Exception: print 'No such file or directory' Does anybody know, how could I, in caught Exception, print the following line? File "C:\Python_tests\Exception_Handling\src\exception_handling.py", line 11, in <module> pkl_file = open('monitor.dat', 'rb') So, program would not exits, and I would have useful information.

  • how can I store the current status of the game in cocos2d ?

    - by srikanth rongali
    I am writing a shooting game in cocos2d. And each enemy enters the screen after the current one is dead. I have stores the enemies and their properties in plist. I need to save the current state of the game. If any phone call comes the game should be started from the current state. So, I usedNsUserDefaults in this way, - (void) applicationDidFinishLaunching:(UIApplication*)application { ... NSUserDefaults *myDefaultOptions = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; //tempCount4 is the current Enemy number. It was declared in another class. I am using extern and using the value here. tempCount4 = [[myDefaultOptions stringForKey:@"enemyNumber"]intValue] ; } - (void)applicationWillTerminate:(UIApplication *)application { [[CCDirector sharedDirector] end]; [myDefaultOptions setObject:tempCount4 forKey:@"enemyNumber"]; } The control is not entering in to the (void)applicationWillTerminate:(UIApplication *)application when I pressed the Home button. And when I touched the game icon on the screen the game is running from first screen and in log (terminal )it is not showing any values. And what should I store to resume my game from stored state. Can you explain where I was wrong ? Thank You.

  • On android how would I go about creating a prompt for an app that requires a user to enter a username before fully launching the app?

    - by racl101
    I'll preface this with I'm really new to working on Android. So I have to work on an existing app and create a screen that prompts the user for a username if one isn't entered then it won't launch the currently existing main activity (i.e. it won't fully launch the app. Instead it will just sit on that screen until a username is entered.) I suppose that it's tantamount to a web app login page in that it will not let a user past that page if the user is not authenticated and authorized. However, there's no authentication nor authorization in this app. Instead, on first run a user must simply register with a username and that username gets saved to the database and for any subsequent runs the app's main activity will just start because a user has registered to that phone. In fact, the app will not prompt the user for their name again unless the app gets deleted with all its data and reinstalled again. This implicitly means that I have to save the user's name in the database or some other kind of storage. So I was wondering what would be the best way of doing this in an app with an existing main activity? Should I try to accomplish this on that existing main activity or create a new activity to display this prompt screen and, in effect, block the main activity from running until the user enters their name? Any tutorials or links would be helpful and thank you in advance for any help.

  • Django model class and custom property

    - by dArignac
    Howdy - today a weird problem occured to me: I have a modle class in Django and added a custom property to it that shall not be saved into the database and therefore is not represent in the models structure: class Category(models.Model): groups = models.ManyToManyField(Group) title = defaultdict() Now, when I'm within the shell or writing a test and I do the following: c1 = Category.objects.create() c1.title['de'] = 'german title' print c1.title['de'] # prints "german title" c2 = Category.objects.create() print c2.title['de'] # prints "german title" <-- WTF? It seems that 'title' is kind of global. If I change title to a simple string it works as expected, so it has to do something with the dict? I also tried setting title as a property: title = property(_title) But that did not work, too. So, how can I solve this? Thank you in advance! enter code here

  • What is Java Message Service (JMS) for?

    - by Daniel
    I am currently evaluating JMS and I don't get what I could use it for. Currently, I believe this would be a Usecase: I want to create a SalesInvoice PDF and print it when an SalesOrder leaves the Warehouse, so during the Delivery transaction I could send a transactional print request which just begins when the SalesOrder transaction completes successfully. Now I found out most JMS products are standalone server. Why would a need a Standalone Server for Message Processing, vs. e.g. some simple inproc processing with Quartz scheduler? How does it interact with my application? Isn't it much too slow? What are Usecases you already implemented successfully?

    So I've created an ADT which is a singly linked list made up of nodes. These Nodes each have a pointer to an object in them called data. Class Structure { struct Node { Object *data; Node *next; }; }; Node *head; I am trying to call a function in the object, like this: head = new Node; head -> data = new Object(); head -> next = NULL; cout << head -> data.print(); I keep getting the following error at compile. error: request for member 'print' in 'head-Structure::Node::data', which is of non-class type 'Object'*

  • String loops in Python

    - by Steve Hunter
    I have two pools of strings and I would like to do a loop over both. For example, if I want to put two labeled apples in one plate I'll write: basket1 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit1 in basket1: basket2 = ['apple#1', 'apple#2', 'apple#3', 'apple#4'] for fruit2 in basket2: if fruit1 == fruit2: print 'Oops!' else: print "New Plate = %s and %s" % (fruit1, fruit2) However, I don't want order to matter -- for example I am considering apple#1-apple#2 equivalent to apple#2-apple#1. What's the easiest way to code this? I'm thinking about making a counter in the second loop to track the second basket and not starting from the point-zero in the second loop every time.

  • SSRS 2008 Report.GetDefaultPageSettings returns incorrect information

    - by jhale
    I have an application that retrieves a report from SSRS 2008 and prints it automatically. This works except it always prints the report in Letter/Portrait. This particular report is Letter/Landscape. I have tracked the problem down to when calling the Report.GetDefaultPageSettings() function for this report, it returns PaperSize.Height = 1100 and PaperSize.Width = 850. I even modified the report to a custom size of 11" x 8.4" and it still returns 850 for the width. I cannot get this to print correctly when it renders the image incorrectly based on these settings. The report prints correctly when accessed by a web browser. It is only when I am trying to automatically print it that the issue appears.

    I bought a Canon MF3200 and used it on an old Windows laptop. The laptop broke, and now I'm trying to setup the printer on a laptop with Windows 7. I downloaded the new driver, and Windows was able to install it and mark it "Ready to Go." But whenever I try to print, an error comes up and it doesn't print. I tried to troubleshoot, to no avail. What else can I do? Any ideas on what the error might be?

  • Why is Rake not able to invoke multiple tasks consecutively?

    - by PandaWood
    I have a Rake task which I have simplified below. I'm using Ruby 1.9 on Windows. Perhaps you would like to guess the outcome of calling the Rake task "list_all_levels" below? It should be: "Hello level 1" "Hello level 2" "Hello level 3" But for reasons unknown to me, it prints only "Hello level 1" and then stops. That is, it always invokes only the first task. If I change the first line to pass the arg "42", it would print "Hello level 42" and then stop. I'm wondering why does it not invoke the task 3 times and print all 3 lines? And is there any way to get it to work how I would expect? task :list_all_levels => [] do Rake::Task[:list].invoke 1 Rake::Task[:list].invoke 2 Rake::Task[:list].invoke 3 end task :list, [:level] => [] do |t, args| puts "Hello level #{args.level}" end

  • making a programming language

    - by None
    I was wondering which way would create a faster programming language, because I have tried both. Writing code that takes the text, splits it by whitespace or newlines or something, then processes each line and has a dictionary for variables. Or writing code that takes text and converts it to another programming language. This is an example of how a very simple version of the first way would be programmed in python: def run(code): text = code.split(";") for t in text: if t == "hello": print "hi" second: def run(code): rcode = "" text = code.split(";") for t in text: if t == "hello": rcode += "print 'hi'"

  • What is the difference between panic and an assert?

    - by acidzombie24
    Go doesn't provide assertions. They are undeniably convenient, but our experience has been that programmers use them as a crutch to avoid thinking about proper error handling and reporting. However it has print and println which does panic like print, aborts execution after printing panicln like println, aborts execution after printing Isnt that the same thing as an assert? Why would they claim the above but have panic? i can see it leading to the same problems but adding an error msg to the end of it which can easily be abused. Am i missing something?

  • Breaking up large DataGridView for printing

    - by Hal
    Hey, I've got a single-row, 40 column-long DataGridView that i need to print. Since i can neither print it directly (because A4 sheets won't cut it ;)) nor adjust its width to the width of the page itself (because the headers look terrible), i wanted to break the DataGridView to 4 separate pieces and display 10 columns per row (imagine: column 1 to 10 in the first line, column 11 to 21 four or five lines below, etc...). Is there an easy way to do this? I was leaning towards a more manual approach (using fors), but i'd love to know if there's a more elegant way. Cheers

  • Comparing Each Character in Java String

    - by user2760357
    I am a beginner at java, and I am trying to create two strings and compare each character. If there is a matching character or characters, the code has to print out the length of each string, without the matching characters. For example, if one string is "super," and the other is "perfect," the program should interpret the strings as superfect, and print out 9 However, if there is no matching part, like pencil and eraser, the code should printout 12, which is the length of two strings combined. Right now, I am having a problem with comparing each character, since I tried to use if(input_word.compareToIgnoreCase(input_word2) != 0) but it only compared the string as a whole.. any suggestion? Thank you for your efforts

  • How can I initialize a 2d array in Perl?

    How do I initialize a 2d array in perl? I am trying the following code: 0 use strict; 10 my @frame_events = (((1) x 10), ((1) x 10)); 20 print "$frame_events[1][1]\n"; but it gives the following error: Can't use string ("1") as an ARRAY ref while "strict refs" in use at ./dyn_pf.pl line 20. This syntax only seems to initialize a 1d array as print "$frame_events[1]\n" works. Though perl doesn't give any error during the assignment.
