  • Inspiration and influence of the else clause of loop statements in Python?

    - by Aristide
    Python offers an optional else clause in loop statements, which is executed if and only if the loop is not terminated by a break. For an interesting discussion about this neglected commodity, see this question. Here, I just wanted to know: if the very concept of this loop-else construct originates from another language (either theoretical or actually implemented), conversely, if it was taken up in any newer language. May be I should ask the former to Guido, but he surely is a too busy guy for such a futile inquiry. ;-)

    I have a problem with Minitab (a statistics program). When I enter my general model and want to see the results, the program warns me: too few arguments or space missing. Everything seems true, and I can't determine where the problem is. Could anyone help me on this subject?

  • Python PLY zero or more occurrences of a parsing item

    - by None
    I am using Python with PLY to parse LISP-like S-Expressions and when parsing a function call there can be zero or more arguments. How can I put this into the yacc code. This is my function so far: def p_EXPR(p): '''EXPR : NUMBER | STRING | LPAREN funcname [EXPR] RPAREN''' if len(p) == 2: p[0] = p[1] else: p[0] = ("Call", p[2], p[3:-1]) I need to replace "[EXPR]" with something that allows zero or more EXPR's. How can I do this?

  • mathing string in python

    - by nani
    Write two functions, called countSubStringMatch and countSubStringMatchRecursive that take two arguments, a key string and a target string. These functions iteratively and recursively count the number of instances of the key in the target string. You should complete definitions forthe remaining problems, we are going to explore other substring matching ideas. These problems can be solved with either an iterative function or a recursive one. You are welcome to use either approach, though you may find iterative approaches more intuitive in these cases of matching linear structures

  • Please help with choosing CI build tool

    - by alexeypro
    Hello, I need to choose the right CI build tool which will: 1. Support groups of build configurations so we can use the standardized build process for all our projects 2. Support dashboard with "pretty" (for executive/director "eye" :-) reports. 3. Support Java, Maven, Ant, and be somewhat customizable for build process itself (though this is optional, as I can "fix" it with scripts) I'd prefer free and open source tool, but paid version is fine too. Please help :-)

    With the latest changes to the developer agreement by Apple, how inherant is the risk of using any kind of framework to develop Apps for devices now?

  • Pass parameters to Flash Main (Document) class

    - by loto
    In Flash CSn/AS3 you associate a Main class with a flash file which when loaded in the flash player "automatically creates an instance of the program's main class." I'd like to know how to pass arguments to the main class, since you don't write it yourself (you put its name in the Document textfield in the IDE).

    - by Allen Bargi
    I'm joining a start up and there's a debate on which platform we should choose for our development; Mac, Linux or Windows? We're gonna use mainly open source tools and languages like, ruby, rails, PHP and mysql and photoshop (or something equivalent on Linux) for design.

  • ValueError: Too Many Values to Unpack Aptana Studio 3

    - by GTyler
    I am working on exercise 13 from learnpythonthehardway.org. I should run this code: from sys import argv script, first, second, third = argv print "The script is called:", script print "Your first variable is:", first print "Your second variable is:", second print "Your third variable is:", third Then enter "python ex13.py first 2nd 3rd" on command line. However, I am using Aptana Studio 3 on Vista and I get the "ValueError: too many values to unpack" error. I am new to Python and Aptana so how can I enter the separate arguments here?

  • wchar to char in c++

    - by Chris
    I have a Windows CE console application that's entry point looks like this int _tmain(int argc, _TCHAR* argv[]) I want to check the contents of argv[1] for "-s" convert argv[2] into an integer. I am having trouble narrowing the arguments or accessing them to test. I initially tried the following with little success if (argv[1] == L"-s") I also tried using the narrow function of wostringstream on each character but this crashed the application. Can anyone shed some light? Thanks

  • Why cast null before checking if object is equal to null?

    - by jacerhea
    I was looking through the "Domain Oriented N-Layered .NET 4.0 Sample App" project and ran across some code that I do not understand. In this project they often use syntax like the following to check arguments for null: public GenericRepository(IQueryableContext context,ITraceManager traceManager) { if (context == (IQueryableContext)null) throw new ArgumentNullException("context", Resources.Messages.exception_ContainerCannotBeNull); Why would you cast null to the type of the object you are checking for null?

  • Passing variables, creating instances, self, The mechanics and usage of classes: need explenation

    - by Baf
    I've been sitting over this the whole day and Im a little tired already so please excuse me being brief. Im new to python. I just rewrrote a working program, into a bunch of functions in a class and everzthings messed up. I dont know if its me but Im very surprised i couldn t find a beginners tutorial on how to handle classes on the web so I have a few questions. First of all, in the init section of the class i have declared a bunch of variables with self.variable=something. Is it correct that i should be able to access/modify these variables in every function of the class by using self.variable in that function? In other words by declaring self.variable i have made these variables, global variables in the scope of the class right? If not how do i handle self. ? Secondly how do i correctly pass arguments to the class? some example code would be cool. thirdly how do i call a function of the class outside of the class scope? some example code would be cool. fouthly how do I create an Instance of the class INITIALCLASS in another class OTHERCLASS, passing variables from OTHERCLASS to INITIALCLASS? some example code would be cool. I Want to call a function from OTHERCLASS with arguments from INITIALCLASS. What Ive done so far is. class OTHERCLASS(): def __init__(self,variable1,variable2,variable3): self.variable1=variable1 self.variable2=variable2 self.variable3=variable3 def someotherfunction(self): something=somecode(using self.variable3) self.variable2.append(something) print self.variable2 def somemorefunctions(self): self.variable2.append(variable1) class INITIALCLASS(): def __init__(self): self.variable1=value1 self.variable2=[] self.variable3='' self.DoIt=OTHERCLASS(variable1,variable2,variable3) def somefunction(self): variable3=Somecode #tried this self.DoIt.someotherfunctions() #and this DoIt.someotherfunctions() I clearly havent understood how to pass variables to classes or how to handle self, when to use it and when not, I probably also havent understood how to properly create an isntance of a class. In general i havent udnerstood the mechanics of classes So please help me and explain it to me like i have no Idea( which i dont it seems). Or point me to a thorough video, or readable tutorial. All i find on the web is super simple examples, that didnt help me much. Or just very short definitions of classes and class methods instances etc. I can send you my original code if you guys want, but its quite long. Thanks for the Help Much appreciated!

  • What is the best approach using JDBC for parameterizing an IN clause?

    - by Uri
    Say that I have a query of the form SELECT * FROM MYTABLE WHERE MYCOL in (?) And I want to parameterize the arguments to in. Is there a straightforward way to do this in Java with JDBC, in a way that could work on multiple databases without modifying the SQL itself? The closest question I've found had to do with C#, I'm wondering if there is something different for Java/JDBC.
