Working with string and json in python (json.loads json.dumps) [duplicate]

Question

I have the following string:

 results = "{'eventid': '766', 'category': '0', 'uptime': '0', 'severity': '0', 'traptime': '0', 'formatline': '0', 'hostname': '0', 'community': '0', 'agentip': '192.168.250.50', 'eventname': '1.3.6.1.2.1.1.3.0', 'timestamp': '17-12-2015', 'trapoid': '0', 'enterprise': '0'}, {'eventid': '1.3.6.1.4.1.3955.2.7.1', 'category': '0', 'uptime': '0', 'severity': '0', 'traptime': '0', 'formatline': '0', 'hostname': '0', 'community': '0', 'agentip': '192.168.250.50', 'eventname': '1.3.6.1.6.3.1.1.4.1.0', 'timestamp': '17-12-2015', 'trapoid': '0', 'enterprise': '0'}"

And I would like to parse it to JSON. My attempts:

results = json.loads(results)

Gives me a

ValueError: Expecting property name: line 1 column 2 (char 1)

Changing the string to:

results = "'details': {'eventid': '766', 'category': '0', 'uptime': '0', 'severity': '0', 'traptime': '0', 'formatline': '0', 'hostname': '0', 'community': '0', 'agentip': '192.168.250.50', 'eventname': '1.3.6.1.2.1.1.3.0', 'timestamp': '17-12-2015', 'trapoid': '0', 'enterprise': '0'}, {'eventid': '1.3.6.1.4.1.3955.2.7.1', 'category': '0', 'uptime': '0', 'severity': '0', 'traptime': '0', 'formatline': '0', 'hostname': '0', 'community': '0', 'agentip': '192.168.250.50', 'eventname': '1.3.6.1.6.3.1.1.4.1.0', 'timestamp': '17-12-2015', 'trapoid': '0', 'enterprise': '0'}"

Gives me

ValueError: No JSON object could be decoded

Answer 1

This is not a valid JSON since it has single quotes and not double quotes.

One option would be to safely eval this string with ast.literal_eval():

>>> from ast import literal_eval
>>> results = "{'eventid': '766', 'category': '0', 'uptime': '0', 'severity': '0', 'traptime': '0', 'formatline': '0', 'hostname': '0', 'community': '0', 'agentip': '192.168.250.50', 'eventname': '1.3.6.1.2.1.1.3.0', 'timestamp': '17-12-2015', 'trapoid': '0', 'enterprise': '0'}, {'eventid': '1.3.6.1.4.1.3955.2.7.1', 'category': '0', 'uptime': '0', 'severity': '0', 'traptime': '0', 'formatline': '0', 'hostname': '0', 'community': '0', 'agentip': '192.168.250.50', 'eventname': '1.3.6.1.6.3.1.1.4.1.0', 'timestamp': '17-12-2015', 'trapoid': '0', 'enterprise': '0'}"
>>> literal_eval(results)[0]['eventid']
'766'
