Answer 1

>>> json_data['latlon'] = ','.join(json_data[k] for k in ('latitude', 'longitude'))
>>> json_data['latlon']
'40.333333,-79.34343'

Note that this will preserve the original key-value pair.

UPDATE:

If you want to remove the original key-value pair use pop method:

>>> json_data['latlon'] = ','.join(json_data.pop(k) for k in ('latitude', 'longitude'))
>>> json_data['latlon']
'40.333333,-79.34343'

Answer 2

data['latlong'] = data['latitude'] + ',' + data['longitude']
del data['latitude']
del data['longitude']

Answer 3

Can be done in one line.

>>> dic = {'latitude': '40.333333', 'longitude': '-79.34343'}
>>>
>>> dic['latlon'] = "{0},{1}".format(dic.pop('latitude'),dic.pop('longitude'))
>>> dic
{'latlon': '40.333333,-79.34343'}

To understand how dic.pop() work, see this.
