Converting a string to dictionary in Python Value Error

I have tried different options to convert a string to dictionary.



My string looks like this:



'severity_label': 'Major', 'ne_reported_time': 1475424546, 'node_id': 54357, 'prob_cause_string': None


When i use



 a_dict = dict([x.strip('').split(":"),]) 


it gives me an error:



Traceback (most recent call last):
File "<pyshell#168>", line 1, in <module>
a_dict = dict([x.strip('').split(":"),])
ValueError: dictionary update sequence element #0 has length 121; 2 is required


I am running this on Python3. Also tried various other options things not working. Any help appreciated.

    You got the right answer (using ast.literal_eval()) but you should really consider why you have a Python dictionary string representation in the first place. That is not a sane format to pass around information. Better use JSON or any other standard format. Or at least pickled data, as that is meant to be a serialization format.

Actually this is not JSON. This is a representation of a python object (like using the repr function).



The most safe way to convert this back to a python object is to use the ast.literal_eval function.

    You should use json.loads



    import json
    a = '"severity_label": "Major", "ne_reported_time": 1475424546, "node_id": 54357, "prob_cause_string": null'
    d = json.loads(a)


    Note I replaced ' by " and None by null

      Why not to use Python 3's inbuilt ast library's function literal_eval. It is better to use literal_eval instead of eval



      import ast
      str_of_dict = "'key1': 'key1value', 'key2': 'key2value'"
      ast.literal_eval(str_of_dict)


      will give output as actual Dictionary



      'key1': 'key1value', 'key2': 'key2value'


      This is easy as you like.

        That string really is valid JSON, I think. Just use the json.loads functionality to get a dictionary.
