python - Iterate over nested dictionary

Question

Is there an easy way of iterating over nested dictionary, which may consist of other objects like lists, tuples, then again dictionaries so that iteration covers all the elements of these other objects?

For example, if I type a key of a nested dictionary object, I would get it all listed in the Python interpreter.

[edit] here is example dictionary:

{
'key_1': 'value_1',
'key_2': {'key_21': [(2100, 2101), (2110, 2111)],
      'key_22': ['l1', 'l2'],
      'key_23': {'key_231': 'v'},
      'key_24': {'key_241': 502,
             'key_242': [(5, 0), (7, 0)],
             'key_243': {'key_2431': [0, 0],
                 'key_2432': 504,
                 'key_2433': [(11451, 0), (11452, 0)]
                },
             'key_244': {'key_2441': {'key_24411': {'key_244111': 'v_24411',
                                'key_244112': [(5549, 0)]
                               },
                          'key_24412':'v_24412'
                         },
                 'key_2441': ['ll1', 'll2']
                }
            },
     }
}

sorry for being unreadable, but I did the best that I could.

def recurse(d):
  if type(d)==type({}):
    for k in d:
      recurse(d[k])
  else:
    print d
