Google 财经错误：文字无效答案

【问题标题】：Google Finance error: invalid literalGoogle 财经错误：文字无效
【发布时间】：2018-08-01 14:58:25
【问题描述】：

我正试图为学校做一个个人项目（股市预测），这时谷歌又开始行动了……

我意识到 Google 财经在过去一年里完全是垃圾，但直到今天早上它似乎仍然有些工作。尽管昨天运行良好，但我第一次运行代码时遇到了错误。

所以我尝试从实际库页面运行示例代码：https://pypi.org/project/googlefinance.client/

!pip install googlefinance.client

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)

params = [
    # Dow Jones
    {
        'q': ".DJI",
        'x': "INDEXDJX",
    },
    # NYSE COMPOSITE (DJ)
    {
        'q': "NYA",
        'x': "INDEXNYSEGIS",
    },
    # S&P 500
    {
        'q': ".INX",
        'x': "INDEXSP",
    }
]
period = "1Y"
# get open, high, low, close, volume data (return pandas dataframe)
df = get_prices_data(params, period)
print(df)

还是得到了

---------------------------------------------------------------------------

以前有没有人遇到过这种情况并知道问题出在哪里或如何解决？

或者，单独说明一下，有没有人知道 Google 财经的好替代品？

【问题讨论】：

试试雅虎财经库

@NoahM。我在哪里可以找到那个？我只是从 google.finance 库页面复制粘贴代码，这就是它吐出的内容，而不是它应该在其页面上所说的内容。
@ᴡʜᴀᴄᴋᴀᴍᴀᴅᴏᴏᴅʟᴇ3000 yahoo Finance 也不起作用....YQLResponseMalformedError: Response malformed.

【解决方案1】：

示例代码有问题。如果您访问GitHub Homepage，您将获得最新版本——甚至是小更新。

我稍微修改了client.py，输出没有问题。

【讨论】：

抱歉没有跟进。你想清楚了吗？如果没有，我相信还有其他解决方案。
不，我切换到雅虎财经：\ ...他们都偶尔工作，但雅虎似乎更一致。

【解决方案2】：

在过去的 48 小时左右，".INX" 没有在我的谷歌表格上更新。 .DJI 和 .IXIC 仍在更新中，尽管我认为其中一个最近没有更新。
