Question

I’m great with PHP and trying to learn Python. So forgive me if I’m trying to translate functions too literally, but here’s what I have:

import json
import urllib


url='http://www.example.com/sample.json'
f = urllib.urlopen(url)
data = json.loads(f.read())


for item in data:
    for entry in item:
        print dictionary.keys(entry)

I know that item has type dict because I did print type(item). But when I try to run the code above, I get NameError: name 'dictionary' is not defined — do I need to import a library that defines dictionary functions? If so, which library?

Answer 1

Write

print entry.keys()

instead of

print dictionary.keys(entry)

I’d recommend having a look at the tutorial and the library reference.
