使用 pip install googlefinance.client 安装软件包后,我正在尝试运行 googlefinance.client 1.3.0 文档中的示例代码
from googlefinance.client import get_price_data, get_prices_data, get_prices_time_data
# Dow Jones param = {
'q': ".DJI", # Stock symbol (ex: "AAPL")
'i': "86400", # Interval size in seconds ("86400" = 1 day intervals)
'x': "INDEXDJX", # Stock exchange symbol on which stock is traded (ex: "NASD")
'p': "1Y" # Period (Ex: "1Y" = 1 year) }
# get price data (return pandas dataframe) df = get_price_data(param) print(df)
但是,我没有得到价格数据集,而是得到了一个空数据框
Empty DataFrame
Columns: [Open, High, Low, Close, Volume]
Index: []
我怎样才能解决这个问题?谢谢!
