Answer 4

You can attempt it using this code :

def inputfunction(lists):
 tmpdict = {}
 for element_index in range(len(lists)):
     tmpdict[headers[elementindex]] = lists[element_index]
 return tmpdict

def run(filename):
 filelist = [eachline.split(',') for eachline in open(inputfile,'r')]
 headers = filelist[0]
 values = filelist[1:]
 finallist = []
 for lists in values:
     finallist.append(inputfunction(lists))
 return finallist

Answer 5

import csv
import json

# Constants to make everything easier
CSV_PATH = './csv.csv'
JSON_PATH = './json'

# Reads the file the same way that you did
csv_file = csv.DictReader(open(CSV_PATH, 'r'))

# Created a list and adds the rows to the list
json_list = []
for row in csv_file:
    json_list.append(row)

# Writes the json output to the file
file(JSON_PATH, 'w').write(json.dumps(json_list))
