凑合着用吧

d = {
    'data__key_hello': "world",
    'data__key_bar': "foo",
    'data__a': "b",
    'b': 'c',
}

n = {}
for k, v in d.items():
    keys = k.replace('__', '_').split('_')
    child = n
    for i, key in enumerate(keys):
        child = child.setdefault(key, {} if i < len(keys) - 1 else v)

print n
