Quick question: is there a extra ")" (or missing "(" in line 39?
print("%d) %s" % (i+1, paper['MedlineCitation']['Article']['ArticleTitle']))

#edited for formatting

@sidewinder02139 the syntax is correct: note the first ")" on that line is part of the output string

ThitherShore is correct. Your code wont work until you enumerate papers['PubmedArticle']
Thank you for the example, but please change this soon so as not to confuse others.
I spent a while trying to figure out what was wrong.

While were at it the last line doesn't work either for the same reason, should be:
import json
print(json.dumps(papers['PubmedArticle'][0], indent=2, separators=(',', ':')))

This is awesome thanks and works pretty well. I'm stuck on trying to get the details of the authors in a succinct way, can anybody help with how to do that? paper['MedlineCitation']['Article']['AuthorList'] isnt right....
Thanks in advance!
