sorting - Sort dictionary of dictionaries by value Python ( 3 Level Dict ) -


i have dict this:

{  'int-abc1':      {         'acc1': {'val': -22313.7381693064, 'qua': -241.0},          'acc2': {'val': -1312.940854148, 'qua': -13.0}     },   'int-abc2':      {         'acc1': {'val': -131.2510359399, 'qua' : -23.0},          'acc3': {'val': -131.40521409002, 'qua' : -13.0},         'acc5': {'val': -12312.7688190937, 'qua' : -1313.0}     } }

i need sort 'val' , similar dict out of it.

something work, think if starting python, should learn sorted function in python.

>>> sorted(k.items(), key = lambda x: x[1][0].itervalues().next()['val'])

where k dictionary.

link provided viki.omega9 in answer should starting point.

note: command return list of tuples (or pairs) in sorted order of form:

[(key1, val1), (key2, val2)]

because dictionaries nature unordered.
