Jupyter Notebook, py2.7 get errors on tutorial

[AnneTheAgile]

I wish to use a python notebook, ie jupyter with this library. I could only get the most trivial example to work. Any ideas? thank you! Anne

This works, returning '1' http://objectpath.org/tutorial.html

from objectpath import *
tree1=Tree({"a":1})
tree1.execute("$.a")

None of the complex json example is working;

json3 = '{ "store": { "book": [ { "category": "reference", "author": "Nigel Rees", "title": "Sayings of the Century", "price": 8.95 } ] }}'
tree3=Tree(json3)
tree3.execute("$")  # ("$.store.book[0].price")

Hi,

$ alone is not a proper OP expression. Could you please send me log of tree3.execute("$.store.book[0].price")?

Have you tried to run the code from bare Python 2.7?
