pandas_datareader.data 未返回从开始日期到结束日期的所有股票价值

pandas_datareader.data not returning all stock values from start to end date

我正在尝试使用 pandas_datareader.data 从雅虎获取股票数据,但我一直缺少数据部分。这是我编写的代码。我现在想做的就是 return 开始日期和结束日期之间日期的所有数据

import pandas as pd 

import pandas_datareader.data as web

from datetime import datetime



ibm = web.DataReader('IBM',  'yahoo', datetime(2015,1,1)

datetime(2016,1,1))

现在这是 return正在处理这个:

data

我很困惑,为什么我在尝试创建我的集合时得到了包含所有缺失数据的椭圆。任何帮助将不胜感激!

这就是 pandas 显示结果 (as explained here) 的方式。 pandas 省略了超过 pd.set_option('max_rows', X) 设置的行(我相信 default 是 50)。您可以使用 pd.options.display.max_rows 查看限制。

尝试 ibm.info(),您应该会看到行数比显示的多。

您的查询结果为:

<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 252 entries, 2015-01-02 to 2015-12-31

但在底部显示为(尽管省略了 rows x columns 信息):
