this question has answer here: python function global variables? 6 answers i trying set dictionary staff's salary in python. want create 2 functions, getname() , getsalary() tried: empdic={} def setname(n): empdic={'n':''} and in python interactive 2.7 typed: >>>setname('marson') >>>print empdic {} the result still empty dictionary, how can deal that? you need modify original dict: empdic={} def setname(d, n): d[n] = "" setname(empdic,"marson") print(empdic) {'marson': ''} you creating new local variable empdic in function, using string "n" not name n passed in function.

i wrote recursive program on fortran calculate combinations of npoints of ndim dimensions follows. first wrote program on matlab , running. in fortran, problem after first iteration assigning absurd values list of points, no explanation. give me hand? program main implicit none integer :: ndim, k, npontos, contador,i,iterate, test integer, dimension(:), allocatable :: pontos print*, ' ' print*, 'npoints?' read *, npontos print*, 'ndim?' read *, ndim k=1 contador = 1 open(450,file= 'combination.out',form='formatted',status='unknown') write(450,100) 'comb ','stat ',(' pt ',i,' ',i=1,ndim) write(450,120) ('xxxxxxxxxx ',i=1,ndim+1) allocate(pontos(ndim)) i=1,4 pontos(i)=i end test = iterate(pontos, ndim, npontos,k,contador) end program main recursive integer function iterate(pontos, ndim, npontos, k,contador)

i'm building basic scraping tool, i'm running locally on laptop, backup data cms. the basic procedural script wrote loads urls database , each url, scraps page, saves content database , echoes page saved. the problem when manages go through urls @ once (a few hundreds of @ times), output of script loads progressively in browser. in firefox can see part of echo statements few pages (indicating pages saved), rest comes in batches , @ bottom firefox indicates me "transferring data localhost..." i'm confused because thought when php script runs, outputs , sends response single block, when it's done, , not this, progressively. maybe i'm forgetting in code? think it? here basic structure of script: <?php try { // login cms // connect db urls ($i = 0; $i < count($urls); $i++) { // data page $data = $scraper->getdata($urls[$i]); // store data page if ( $db->save($data) ) { echo 'data saved "'

i'm trying optimize as can react components using purerendermixin , making sure props being passed immutable , don't change render render. one issue i'm running case of mutating bound event handlers passed props. more specifically, have renders , array of children: in parent: onchange: function(key, data) { ... }, render: function() { return this.state.array.map(function(object, index) { return <child key={object.key} onchange={this.onchange.bind(key)} stuff={object.stuff}/> } }) } in child: ... mixins: [purerendermixin] ... it turns out purerendermixin triggers update inside child because onchange prop new instance (even though it's bound same key). is, each call anyfunction.bind(123) generates new value (ie. not ===). how people deal this? here's 2 ways can think of: pass unbound onchange handler, pass key separately, , have child call onchange key -- bit messy adds unecessary complexity child. c

i have binary file (saved dpl ) made shc . here simple source file: #!/bin/bash java -jar /users/eli/documents/dpl.jar $@ it should run jar program arguments. works fine, except there few seconds of delay on startup. noticed in title bar of terminal (os x) switches dpl bash dpl bash few times, until switching java , running jar. don't understand going on here. edit: additionally, actual java program seems slowed down effect. edit2: need binary file can use shell interpreter ( #!/usr/bin/dpl ) try saving .sh file , giving executable permission. chmod +x <your file>.sh

i configuring elmah 1.2 log errors within our ektron 9.1 application, not log 404 errors. elmah functional logging other errors (including unhandled exceptions), not 404 errors. not running mvc environment / 3-tier ektron architecture, still using traditional asp.net / ektron web forms solution. i know elmah logs these errors default, i'm wondering if i'm missing regards how elmah interacting ektron. there's not information out there on topic, , 1 article found dated 2010, information severely outdated. it's different urls end in .aspx , other ones. if user goes site , accesses /thisfileisnothere.html static file handler handle that. ektron replaces static file handler ekdavhttphandlerfactory. ektron's handler doesn't throw exception. doesn't trigger application.error event. sets statuscode 404. if wanted custom log error elmah, hook application.postrequesthandlerexecute , check response.statuscode if user tries go /thispageisnthere.aspx

i wrote managed extension autocad. when autocad loads extension launch iextensionapplication.initialize() method. need method launched in main thread of application. enough set stathread attribute method purpose? attribute requirement or recommendation ? the [stathread] attribute works on main() entrypoint of standalone executable program. promise make operating system, telling main thread of program "well-behaved". must pump message loop , never block. breaking promise causes hard diagnose misbehavior, deadlock common. none of applies when write autocad extension. did not create thread, autocad did. can't make promises, autocad has implement them. nor "main thread", that's term can apply standalone program. the thread calls extension single-threaded apartment, can use thread.getapartmentstate() in code double-check. sta requirement thread displays ui, commonly in extension.
