python CSVをJSONに変换するごく简単なPython中のスクリプト。简単だけど変换の作业がある度に调べる気がするのでメモ。

import csv
import json
csvfile = open('sourcefile.csv', 'r')
jsonfile = open('result.json', 'w')
fieldnames = ("x","y","judge","flag")
reader = csv.DictReader(csvfile, fieldnames)
for row in reader:
  json.dump(row, jsonfile)
  jsonfile.write(',\n')
