why is nested for loop not capturing all values from dictionary - python-3.x

Question

from Allan Visochek's book, practical data wrangling, chp 3,
using python 3, conda 6.0.1
new_scf_data=[]
variables= ["address", "created_at","description","lng","lat","rating"]
for old_entry in scf_data["issues"]:
new_entry={}
for variable in variables:
new_entry[variable] = old_entry[variable]
new_scf_data.append(new_entry)
print(new_entry)
{ 'address': '2501 Granada Circle West Saint Petersburg, Florida',
'created_at': '2017-08-26T16:19:53-04:00',
'description': 'Grass has not been cut in over 3 weeks.',
'lat': 27.7325689,
'lng': -82.6684505,
'rating': 1}
This code should return a nested dictionary with several keys, with their values. However, after running the code, only one "case" of the original dataset. Please keep in mind that im a total noob.
Please advise
much appreciated

Answer 1

I think I may have found the cause. Apparently, Jupyter wasnt running certain lines of code. After further investigation, turns out that the updated version of Tornado was to blame. I downgraded the same, and now im able to run the code w/o any problems.
