Convert unicode string dictionary into dictionary in python

Question

I have unicode u"{'code1':1,'code2':1}" and I want it in dictionary format.

I want it in {'code1':1,'code2':1} format.

I tried unicodedata.normalize('NFKD', my_data).encode('ascii','ignore') but it returns string not dictionary.

Can anyone help me?

Answer 1

You can use literal_eval. You may also want to be sure you are creating a dict and not something else. Instead of assert, use your own error handling.

from ast import literal_eval
from collections import MutableMapping

my_dict = literal_eval(my_str_dict)
assert isinstance(my_dict, MutableMapping)

Answer 2

You can use the builtin eval function to convert the string to a python object

>>> string_dict = u"{'code1':1, 'code2':1}"
>>> eval(string_dict)
{'code1': 1, 'code2': 1}

You can use built-in ast package:

import ast

d = ast.literal_eval("{'code1':1,'code2':1}")

Help on function literal_eval in module ast:

literal_eval(node_or_string)

Safely evaluate an expression node or a string containing a Python expression. The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

EDIT: Turns out my assumption was incorrect; because the keys are not wrapped in double-quote marks (“), the string isn’t JSON. See here for some ways around this.

~~I’m guessing that what you have might be JSON, a.k.a. JavaScript Object Notation.~~

You can use Python’s built-in json module to do this:

import json
result = json.loads(u"{'code1':1,'code2':1}")   # will NOT work; see above

I was getting unicode error when I was reading a json from a file. So this one worked for me.

import ast
job1 = {}
with open('hostdata2.json') as f:
  job1= json.loads(f.read())

f.close()

#print type before converting this from unicode to dic would be <type 'unicode'>

print type(job1)
job1 =  ast.literal_eval(job1)
print "printing type after ast"
print type(job1)
# this should result <type 'dict'>

for each in job1:
 print each
print "printing keys"
print job1.keys()
print "printing values"
print job1.values()
