从多索引DataFrame中检索切片

Question

我有一个带有MultiIndex的Pandas DataFrame，如下所示：

我正在尝试使用IndexSlice检索几行：

idx=pd.IndexSlice
prices.loc[idx[["2016-09-19 13:30:00":"2016-09-19 14:30:00"],"Chinese Renminbioffshore"],:]

但我收到错误：

SyntaxError: invalid syntax

根据the documentation (scroll to in:72)，我应该能够做到这一点。

有人有建议吗？

这里是重新创建数据帧的数据：

编辑：似乎我无法发布数据来重新创建这个数据帧，因为它使问题的代码看起来像代码太大了...希望这个问题仍然可以解决。

EDIT2：也许发布它会有帮助吗？

Answer 1

您应该可以通过将(idx[...], your_value)的元组作为第一个参数传递给loc来实现此目的。

prices.loc[(idx["2016-09-19 13:30:00":"2016-09-19 14:30:00"], xxx), :]

示例：

prices.loc[(idx["2016-09-19 13:30:00":"2016-09-19 14:30:00"], 'Gold'), :]
