我知道使用熊猫这就是你通常获得的每日股价报价。但我想知道是否有可能获得每月或每周报价，是否可以通过一个参数来获得月度报价？
ToString答案 0 :(得分：6)
Yahoo!每月收盘价财务......
import pandas_datareader.data as web
data = web.get_data_yahoo('IBM','01/01/2015',interval='m')
您可以根据需要替换间隔输入（'d'，'w'，'m'等）。

试试这个：
In [175]: from pandas_datareader.data import DataReader
In [176]: ibm = DataReader('IBM', 'yahoo', '2001-01-01', '2012-01-01')
更新仅显示Adj Close的平均值（月开始）
In [12]: ibm.groupby(pd.TimeGrouper(freq='MS'))['Adj Close'].mean()
Out[12]:
