json is not converting to csv in python 3.5 -

- 

#!/usr/bin/env python  import requests import csv import json import sys  s = requests.session()  r = s.get('https://onevideo.aol.com/sessions/login?un=username&pw=password')  r.status_code  if r.status_code == 200:     print("logged in successfully")  else:     print("check username , password")  filename  = open('outputfile3.csv', 'w') sys.stdout = filename data = s.get('https://onevideo.aol.com/reporting/run_existing_report?report_id=102636').json() json_input = json.load(data) entry in json_input:     print(entry)

your assignment of sys.stdout = filename not idiomatic, many people may not understand doing. key misunderstanding appear have python interpret either fact have imported csv or extension of file have opened , automatically write valid lines file given list of dictionaries (which .json gets parsed as).

i present full example of how write dictionary-like data contrived json reproducability:

jsonstr = """     [{"field1": "property11", "field2": "property12"},      {"field1": "property21", "field2": "property22"},      {"field1": "property31", "field2": "property32"}]     """

first, using standard library:

import json import csv  data = json.loads(jsonstr)  open('outputfile3.csv', 'w') f:     writer = csv.dictwriter(f, fieldnames=['field1', 'field2'])     writer.writeheader()     writer.writerows(data)

then more succinctly using pandas:

import pandas  pandas.read_json(jsonstr).to_csv('outputfile3.csv', index=false)

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
