python - How do I return a specific json field? -

how function return value "accounting"?

def getowner():        z = [{u'_ref': u'network/zg5zlm5ldhdvcmskmtaumtawljewmc4wlz90jlza:10.100.100.0/24/default', u'extattrs': {u'owner': {u'value': u'accounting'}}}]        return ((h['value']) h in z['owner'])   z = getowner() print z 

im getting error typeerror: list indices must integers, not str

your z variable array (of 1 element) because of surrounding square brackets. here how access have:

>>> z[0]['extattrs']['owner']['value'] u'accounting'
