Python and CSV: Reading JSON from CSV -


i have function reads csv file , dumps contents file of choice. contents of csv file column each rows contains series of json objects this(validated jsonlint):

 [{"classname": "merchant", "__type": "pointer", "objectid": "s8igowbn8y"}, {"classname": "merchant", "__type": "pointer", "objectid": "psnnxwfvmv"}, {"classname": "merchant", "__type": "pointer", "objectid": "ihcc9ikkbj"}, {"classname": "merchant", "__type": "pointer", "objectid": "rvprbh5nwx"}, {"classname": "merchant", "__type": "pointer", "objectid": "47zjn9rrov"}, {"classname": "merchant", "__type": "pointer", "objectid": "cogtlmgzyo"}, {"classname": "merchant", "__type": "pointer", "objectid": "yjhn9dbcit"}, {"classname": "merchant", "__type": "pointer", "objectid": "neoy9rprd4"}]

to conceptualize bit, want:

csv file ---> function wrote ---> something.json

in case used test.csv input , test.txt output. seems work fine first json stream, there quirk:

the first json object come out fine:

[  {"classname": "merchant", "__type": "pointer", "objectid": "s8igowbn8y"},  {"classname": "merchant", "__type": "pointer", "objectid": "psnnxwfvmv"},  {"classname": "merchant", "__type": "pointer", "objectid": "ihcc9ikkbj"}],

but after that, start coming out this: 

"[{""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""s8igowbn8y""},  {""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"":  ""psnnxwfvmv""},  {""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""ihcc9ikkbj""},  {""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""rvprbh5nwx""},  {""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""47zjn9rrov""},  {""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""cogtlmgzyo""},  {""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""yjhn9dbcit""},   {""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""neoy9rprd4""}',  '\n[{""classname"": ""merchant"", ""__type"": ""pointer"", ""objectid"": ""tnglb9dobr""},

here function this:

def read_csv(thefile):      f = open('test.txt','w')     open(thefile, 'rb') csvfile:          #based on python documentation         spamreader = csv.reader(csvfile, delimiter=']')         row in spamreader:             f.write(str(row))      f.close()

two questions:

  1. how ensure output consistent? in other words, how can eliminate ""'s , newline characters json valid? have nlsparams i'm adding?

  2. eventually, don't want dump .txt file, .json file. how can done?

thanks , responses!

my guess -untested- :

import json open('test.txt','r') input_file:     open('output.json','wb') output_file:         row in input_file.readlines():             output_file.write(json.loads(row))

in case, using lib lot: https://docs.python.org/2/library/json.html

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
