Question

当然你们都知道答案，这很容易，但我是python的新手：）

我在互联网上找到了一段代码，从雅虎财经中读取股票价格

如何安装此模块以使用命令？我正在使用Windows 7和Python 3.xx。

非常感谢！

Answer 1

您只需将其放在与脚本相同的目录中，即可导入它。

如果您想“安装”它，可以将其设置为C:\Python31\Lib\site-packages\ystockquote.py。然后，您应该可以使用import ystockquote导入它。

Answer 2

此代码实际上是用于python 2.x，并且由于python 3不向后兼容，因此无法使用python 3进行编译。我的建议是让你看一下这个code。那个是为python 3编写的，你可以使用win7和python 3来使用它。只需创建一个像test.py这样的文件，将两个文件放在同一目录中，然后编写如下代码：

from Ystock import  *
print (Ystock("GOOG").get_all())
print(Ystock("IBM+GOOG").get_stock_exchange());
print(Ystock("IBM+GOOG").get_dividend_per_share());
