json dict - python how to access

i know, this might be easy, but i am stuck whatsoever.. this is the data

{ u'job_27301': [{u'auto_approve': u'0',
                 u'body_src': u'some text1'}],

  u'job_27302': [{u'auto_approve': u'0',
                 u'body_src': u'some text2'}],

  u'job_27303': [{u'auto_approve': u'0',
                 u'body_src': u'some text3'}] }

I have this dictionary of lists.

how can I loop over it and get body_src from the value list in each step? I tried

for k, d in data:
    print d[k]

to get the list part, but it is saying too many values to unpack...

You're getting that error message because when you iterate directly over a dict you only get the keys.

So you could do this:

for k in data: 
    print data[k][0]['body_src']

output

some text1
some text3
some text2

d={ u'job_27301': [{u'auto_approve': u'0',
                 u'body_src': u'some text1'}],

  u'job_27302': [{u'auto_approve': u'0',
                 u'body_src': u'some text2'}],

  u'job_27303': [{u'auto_approve': u'0',
                 u'body_src': u'some text3'}] }

for k,v in d.iteritems(): # items in python 3
    print(v[0]["body_src"])

Or just the values:

for v in d.itervalues(): # values in python 3
    print(v[0]["body_src"])

In order to iterate over the dict (key,item), you can use data.items() or iteritems():

>>> for k,d in data.iteritems():
...     print d[0][u'body_src']
...
some text1
some text3
some text2

When doing for k,d in data: you try to iterate over the keys only:

>>> for i in data:
...   print i
...
job_27301
job_27303
job_27302
