Reading and Writing JSON through Python -


read.json file : 

{     "username" : "admin",     "password" : "admin",     "iterations" : 5,     "decimal" : 5.5,     "tags" : ["hello", "bye"],     "value" : 5 }

program.py file:

import json  open('read.json') data_file:     data = json.load(data_file)  data = str(data) data.replace("'",'""',10) f = open("write.json", "w") f.write(data)

write.json file : 

{'username': 'admin', 'password': 'admin', 'iterations': 5, 'decimal': 5.5, 'tags': ["hello", "bye"], 'value': 5}

what want achieve :

  1. read json data read.json file
  2. parse , modify values json in program
  3. write write.json file (in json format)

there no errors in code, write.json not contain values in double quotes(""), rather values wrapped in single quotes making not proper json format.

what change needs done make write.json file contain proper json format , 'pretty-write' write.json file.

you can directly dump json data file. docs

import json open('read.json', 'w') outfile:     json.dump(data, outfile, sort_keys=true, indent=4)     # sort_keys, indent optional , used pretty-write

to read json file:

with open('read.json') data_file:         data = json.load(data_file)

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
