Question

I have a dict, that looks like this:

{     'foo': {         'opt1': 1,         'opt2': 2,         },     'foo/bar': {         'opt3': 3,         'opt4': 4,         },     'foo/bar/baz': {         'opt5': 5,         'opt6': 6,         }     } 

And I need to get it to look like:

{     'foo': {         'opt1': 1,         'opt2': 2,         'bar': {             'opt3': 3,             'opt4': 4,             'baz': {                 'opt5': 5,                 'opt6': 6,                 }             }         }     } 

I should point out that there can and will be multiple top-level keys (‘foo’ in this case). I could probably throw something together to get what i need, but I was hoping that there is a solution that’s more efficient.

Like this:

def nest(d):     rv = {}     for key, value in d.iteritems():         node = rv         for part in key.split('/'):             node = node.setdefault(part, {})         node.update(value)     return rv
