问题 JSON array defined in scope: $scope.faq = [ {"Question 1": "Answer1"}, {"Question 2": "Answer2"} ]; HTML: <div ng-repeat="f in faq"> {{f}} </div> Output: {"Question 1": "Answer1"} {"Question 2": "Answer2"} What I want output to look like: Question 1 - Answer1 Question 2 - Answer2 How it seems like it should work: <div ng-repeat="f in faq"> {{f.key}}-{{f.value}} </div> ... but it doesn't. 回答1: Change your json array in scope like; $scope.faq = [ {key: "Question 1", value: "Answer1"}, {key:

I have a simple download script and I use set -x which works great; I can see each step it performs, and I can identify errors in the script or in the download: #!/bin/bash set -x #short_date=$(/bin/date +%m%d%y) short_date=$(/bin/date -d "8 day ago" +%m%d%y) #long_date=$(/bin/date +%Y%m%d) long_date=$(/bin/date -d "8 day ago" +%Y%m%d) scp -v -P 1332 -i /home/casper/.ssh/id_rsa_BANK friendly@192.168.1.10:/home/friendly/transfer/out/EXCHANGE_$short_date.csv /local/casper3/dailymetrics/BANK_$long_date.csv I would like to automate this job.

I've gathered several codes from StackOverflow and a few other sites and edited it to fit my program however while trying to do a block by block encryption using RSA problem is I can only encrypt small text files of size 1 kilobyte. Encryption and Decryption of text files are working fine. However, encrypting pictures and ANY files larger than 1

Java When outputting String and method return, why does method return output first?

阅读更多关于 Java When outputting String and method return, why does method return output first?

问题 In the code below, if the string "Mult" comes before the test1(4) method call, why does the method output before the string? And why does it bounce form outputting the first part of the method, then leaves the method to output the string, then returns to the method to output the method's return value? code: public class Scratch{ public static void main(String[] args){ System.out.println("Mult:" + test1(4)); } public static int test1(int n){ System.out.println("N:" + n); return n*2; } } Output

阅读更多关于 How can I do an atomic write to stdout in python?

I've read in some sources that the print command is not thread-safe and the workaround is to use sys.stdout.write command instead, but still it doesn't work for me and the writing to the STDOUT isn't atomic. Here's a short example (called this file parallelExperiment.py): import os import sys from multiprocessing import Pool def output(msg): msg = '%s%s' % (msg, os.linesep) sys.stdout.write(msg) def func(input): output(u'pid:%d got input \"%s\"' % (os.getpid(), str(input))) def executeFunctionInParallel(funcName, inputsList, maxParallelism): output(u'Executing function %s on input of size %d

问题 It may look like a trivial issue, but I couldn't find any answer through googling. I have this little program : Program Test_spacing_print Integer:: N Real:: A,B N=4; A=1.0; B=100.0 print*,'N =',N print*,'A =',A,' B =',B print '(2(A3,F8.2,1X))' ,'A =',A,' B =',B print 20, A,B 20 format('A =',F8.2,x,'B =',F8.2) End Program Test_spacing_print which gives me the output: N = 4 A = 1.00000000 B = 100.000000 A = 1.00 B 100.00 A = 1.00 B = 100.00 I want to get rid of the unwanted space that I get

There is part of the output: output of gradle dependencies What does the symbols ('+','\','->','()','(*)') exactly mean?
