python实现csv转json格式

import csv
import json

file_path = "your_filePath.csv"
csvfile = open(file_path, 'r')
jsonfile = open('file.json', 'w')

fieldnames = ("Starting Station Latitude", "Starting Station Longitude", "Ending Station Latitude", "Ending Station Longitude")

reader = csv.DictReader( csvfile, fieldnames)

out = json.dumps( [ row for row in reader ] )

jsonfile.write(out)
