用python撰寫查詢股票當月交易情形

Python在資料讀取以及資料操作上，充份展現其簡單易學的特性，台灣股票交易網站網址為：http://www.twse.com.tw/exchangeReport/STOCK_DAY
採用GET操作方式，只要輸入日期和股票號碼(date=%s&stockNo=%s)即可以讀取當月交易情形。

完整的程式如下：
import requests
import json

url = 'http://www.twse.com.tw/exchangeReport/STOCK_DAY?date=%s&stockNo=%s' % ( '20181201', '2892')
r = requests.get(url)
print(r.text)
data =json.loads(r.text)

print(data['title'])
print(data['fields'])

for row in data['data']:
    print(row)

執行結果：
107年12月 2892 第一金           各日成交資訊
