Right
So your dict (which is dicts !) we have
>>> json.keys()
['1', '3', '2', '4']
And so
>>> json[0]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: 0
>>> json['0']
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
KeyError: '0'
>>> json['1']
{'Status': 'Submitted', 'Startdate': ['01/01/2011'], 'Enddate': ['02/02/2012'],
'Job_ID': 1, 'm_Quantile': '80', 'Allocation_3': ['50'], 'm_Method':
'Distributed', 'm_Controller': 'Python', 'Allocation_2': ['30'],
'Allocation_1': ['20'], 'Asset_2': ['YHOO'], 'Note': '', 'VaR': '', 'submit':
['Submit'], 'm_Iterations': '1000', 'Asset_3': ['CAT'], 'Asset_1': ['AAPL']}
IOW 0 is not a key
Neither is '0' (the string containing the char 0)
But the string '1' is a valid key
