Question

I have a json document (as_stats.json) that looks something like this:

{"failed":5, "received": {"192.168.5.2": 40, "192.168.5.45": 84, "127.0.0.1": 145}}

My python code looks like this:

import json,urllib
data = open('as_stats.json').read()
d = json.loads(data)

for x in d['received']:
    if (x != '127.0.0.1'):
        print x

The values returned are the IP addresses, which are variables i.e. the could change any time to any other address. What I am interested in is the number of files received from each IP address as well. When I try rewriting my code as

for x,y in d['received']:
        if (x <> '127.0.0.1'):
            print x,y

I get a message saying “too many values to unpack”.

How do I go about getting the values that I want from the key-value pairs?

Answer 1

Use:

for x,y in d['received'].iteritems():

Normal iteration over a dict will give you only the keys. Use itervalues to get the values, or iteritems to get both keys and values.
