I'm not aware of any ready-made code. But you can just get the boolean
matrix by using ``apply`` and a one-hot encoder.
Why are you interested in a single leave? the query seems to be able to
return "only" a single boolean.
It is probably more efficient to traverse the full tree for each data
point if you are interested in all the leafs.

Hi everyone,
Is it possible to extract the decision tree rule associated with each
leaf node into a Pandas Dataframe query
<http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.query.html>?
So that one can view the corresponding Dataframe content by feeding in
the decision rule.
Best,
Rex
