一次抓取多筆代號股票之31日交易資料？

[chingwen823]

有沒有一次抓取的方法？
ex. restock.Stock(['2330','6515'])

try with list got en error back:

stock = twstock.Stock(stocknum)
2
stock

TypeError Traceback (most recent call last)
in ()
----> 1 stock = twstock.Stock(stocknum)
2 stock

~/Library/Python/3.6/lib/python/site-packages/twstock/stock.py in init(self, sid, initial_fetch)
133 def init(self, sid: str, initial_fetch: bool=True):
134 self.sid = sid
--> 135 self.fetcher = TWSEFetcher() if codes[sid].market == '上市' else TPEXFetcher()
136 self.raw_data = []
137 self.data = []

TypeError: unhashable type: 'list'

You can try this:

stocks = [Stock(symbol) for symbol in ['2330', '6515']]

I don't think it's a good idea to allow Stock(['2330', '6515']).
Maybe you can elaborate more on your use case?

thanks you are right
what I trying to do is to compare a group of stocks with another

I will maintain a local dataset instead

by the way , the time limitation of connections of twes seems to be 3times/5sec

[ianlini]

Yeah, it's very easy to be banned by TWSE. I always add a 1~5s random sleep between each request.

[chingwen823]

我很好奇 一般限制是單位時間裡的連線數
如果不重建connection，連線的sesssion沒斷 應該可以一直無限去下查詢？？（就不會被ban是嗎？）

[ianlini]

我有想過這個問題，不過沒有測試過
另外 user agent 可能也有影響
不知道有沒有人測試過？

@chingwen823

要如何作到不重建 connection 但是可以換查詢？

[chingwen823]

我不知道 我後來自已寫了一套

那真的不重建連線就能一直查下去不被封嗎
