i have found nice examples ( here , here ) of implementing sicp-like streams in python. still not sure how handle example integral found in sicp 3.5.3 " streams signals ." the scheme code found there is (define (integral integrand initial-value dt) (define int (cons-stream initial-value (add-streams (scale-stream integrand dt) int))) int) what tricky 1 returned stream int defined in terms of (i.e., stream int used in definition of stream int ). i believe python have expressive , succinct... not sure how. question is, analogous stream-y construct in python? (what mean stream subject of 3.5 in sicp, briefly, construct (like python generator) returns successive elements of sequence of indefinite length, , can combined , processed operations such add-streams , scale-stream respect streams' lazy character.) there 2 ways read question. first simply: how use stream constructs, perhaps ones second

suppose have low level work java class public method input parameters , other private methods manipulate input data . preferable approach : set input data member fields no need pass between private methods, or pass parameters private methods? the issue here isn't passing value between private methods, it's how perceive state of object. in other words, make sense instance retain value of parameter passed. consider, example, builder class styled after bob builder - fixes many things, once he's done fixing something, it's fixed. it's no longer related bob. on other hand, wears helmet, , takes him wherever goes - part of state: public class builder { private string name; private helmet helmet; public builder(string name) { this.name = name; } /* helmet methods - helmet data member */ public void wearhelmet(helmet helmet) { this.helmet = helmet; } public void adjusthelmet() { helmet.adjust();

i'm putting code base unity3d sorts of common patterns. imported project source code not compiled dll. some of code should compiled specific dependency (also installed source code) present. (in case, networking code should compiled if photon installed in project). i go through manually delete files aren't required, prefer kind of automated way conditionally compile classes. if python like: try: import mylibrary class myclass(self): ... except importerror: # library not imported i know within class can use reflection work out if class defined, there way @ higher level, i.e. pseudocode: #if namespace_defined('externaldependency') // <-- how can kind of check? using externaldependency; public class myclass { ... } #endif in c#, there's no chance include using clause in code file part of project doesn't reference assembly contains imported namespace, thus, won't able perform check. an using of namespace can

i have 2 worksheets: everyone eventbrite in everyone have column taken email addresses. columns c z full of other data. in eventbrite have column taken email addresses. column b course so looking in everyone , column b populated corresponding course i have tried following in b2 #ref error =vlookup(a2,eventbrite!a:a,2,0) please try this: =vlookup(a2,eventbrite!a:b,2,0) hope help.

i have table in postgresql database looks this: stid | e5 | e10 | diesel | date -----+------+------+--------+------------------------ e850 | 1300 | 1400 | 1500 | 2016-05-02 05:30:01+02 e850 | 1400 | 1500 | 1700 | 2016-05-02 08:30:01+02 e850 | 1300 | 1400 | 1500 | 2016-05-02 21:00:01+02 e850 | 1200 | 1300 | 1350 | 2016-05-03 10:30:01+02 e850 | 1300 | 1400 | 1500 | 2016-05-03 21:00:01+02 954d | 1200 | 1100 | 1300 | 2016-05-02 03:30:01+02 954d | 1300 | 1100 | 1300 | 2016-05-02 15:00:01+02 954d | 1400 | 1800 | 1400 | 2016-05-02 22:30:01+02 954d | 1700 | 1900 | 1400 | 2016-05-03 09:30:01+02 954d | 1500 | 1900 | 1200 | 2016-05-03 23:30:01+02 so have unique id's (stid), prices (e5,e10,diesel) , timestamp (date) indicates when price introduced. want calculate average price per day , stid, weighted duration price charged. , want take period between 8 , 8 pm account. to calculate weighted average price of e5 stid e850 , date 2016-05-02 between 8 , 8 pm follo

my program looks this: from threading import thread import time def something(): time.sleep(10) def function1(): if condition1: thread(target=something).start() def function2(): if condition2: thread(target=something).start() def function3(): if condition3: thread(target=something).start() def main(): thread(target=function1).start() thread(target=function2).start() thread(target=function3).start() main() if function 1 has spawned thread calling something() ,i dont want functions 2 , 3 spawn thread calling something(). actually code creates 3 independent threads , each of these threads can create thread doing something, again independent of each other (so getting 3 soemthing threads @ max). ask these threads interact in manner: "something" should executed once. hence thread "something" must instantiated 1 time , call must secured lock. function threads must know "something" thread,

the problem: i'm trying write recursive method prints of digits in number or greater first digit , lower last digit. accomplished write recursive method prints of digits or lower last digit. can't figure out how check if digit grater first digit. examples: for print(325648) print 5, 6, 4. for print(237) print 3. for print(925648) not print digit. this code: public static void print(int n) { print(n,n%10); } private static void print(int n,int lastdigit) { if(n==0) return; if(n%10<lastdigit) system.out.println(n%10); print(n/10,lastdigit); } the requirement of method: not allowed use loops(or methods loops). allowed use 1 recursive transition. the length of number not known. the method can change number, @ end of operation number should same @ beginning. please note: not homework assignment! i'm writing method practice exam talking tomorrow. the idea here recurse dividing 10 until number reduced first

hi guys item prices in system generated system , round up. like this: 1.01 1.49 1.50 , 1.51 1.99 2.00 examples: 5.56 -> 6.00 , 5.32 -> 5.50 how can achieve this? thank you. rounding done using math.ceiling method. applying method directly round nearest dollar. trick rounding nearest 50 cents double price, take ceiling, , returning half of result: decimal roundedtofiftycents = math.ceiling(2 * originalprice) / 2; demo.

given 2 numbers a and b, have find nth number divisible by a or b. input : first line consists of integer t, denoting number of test cases. second line contains 3 integers a, b and n . output : each test case, print nth number in new line. constraints : 1≤t≤10^5 1≤a,b≤10^4 1≤n≤10^9 sample input 1 2 3 10 sample output 15 explanation numbers divisible by 2 or 3 are: 2,3,4,6,8,9,10,12,14,15 and 10th number is 15. my code (in c) : #include<stdio.h> int main() { long long int i,a,b,n,j,c=0,small; scanf("%lld",&i); while(i--) { scanf("%lld%lld%lld",&a,&b,&n); if(a==b) { printf("%lld ",a*n); return 0; } else { if(a>b) small = b ; else small = ; for(j=small;1;j++) { if(j%a==0 || j%b==0) c++ ; if(c

from ios 8.0+, supposed use wkwebview , in official apple documentation , add setting view wkwebview. need add subview, numerous reasons. i have add buttons/labels above wkwebview . i can add adding uiview storyboard , setting code wkwebview , looks neater adding code. my code: @iboutlet weak var container: uiview! private var wkwebview: wkwebview! override func loadview() { let webconfig = wkwebviewconfiguration() wkwebview = wkwebview(frame: .zero, configuration: webconfig) wkwebview.uidelegate = self } override func viewdidload() { super.viewdidload() container = wkwebview let url = url(string: "https://google.com") let request = urlrequest(url: url!) wkwebview.load(request) } i have tried this: wkwebview add subview i have tried container.addsubview method, crashed nil pointer. every time load app, there's black screen. any ideas? you should add instance of wkwebview subview given view: view.addsu
