一次抓取多筆代號股票之31日交易資料？ #41

Open chingwen823 opened 6 years ago

chingwen823 commented 6 years ago

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?

chingwen823 commented 6 years ago

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 commented 6 years ago

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

chingwen823 commented 6 years ago

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 commented 6 years ago

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？

要如何作到不重建 connection 但是可以換查詢？

chingwen823 commented 5 years ago

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
