I like to perform what I call "objectify" on nested dictionary type
stuff into classes.
class TestPart(object):
def __init__(self, **kwargs):
for k,v in kwargs.items():
setattr(self, k, v)
class Test(object):
def __init__(self):
self.name = None
self.entries = []
def set(self, name, listofdicts):
self.name = name
for l in listofdicts:
self.entries.append(TestPart(**l))
def search(self, key, value):
rets = []
for t in self.entries:
if value in getattr(t, key):
rets.append(t)
return rets
if __name__ == "__main__":
d = {'252': [{'code': '51679', 'date': '2009-08-01 11:35:38',
'userfield':
'252', 'from': '9876662881', 'to': '19877760406',
'fpld': '"Foobar" <9855562881>', 'result': 'ANSW', 'sec':
131}, {'code': '51679',
'date': '2009-08-01 14:33:55', 'userfield': '252',
'from':
'9876662881', 'to': '19877770391', 'fpld': '"Foobar"
<9876555881>',
'result': 'ANSW', 'sec': 86}]}
items = []
for k, v in d.items():
t = Test()
t.set(k, v)
items.append(t)
for i in items:
got = i.search("code", "9")
print got
for r in got:
print r.code
It's not quite right, but you get the basic idea. I just find it
easier to wrap my head around structures built like this rather than
trying to remember alot of inner/outer, index variables, etc.
