Examples

>>> sample_data = {'some': {'nested': {'entry': 100, 'structure': 200},
...                         'subkey': 10},
...                'topentry': 1}
>>> flat = flatten(sample_data)
>>> for k in sorted(flat):
...     print(repr(k), ':', flat[k])
'some.nested.entry' : 100
'some.nested.structure' : 200
'some.subkey' : 10
'topentry' : 1
