Convert string dictionary to dictionary in Python

PythonServer Side ProgrammingProgramming

In this article we'll see how to convert a given dictionary containing strings into a normal dictionary of key value pairs.

With json.loads

The json.loads can pass a given string and give us the result as normal strings preserving the structure of the data. So we pass the given string dictionary into this function as a parameter and get our result.

Example

 Live Demo

import json
stringA = '{"Mon" : 3, "Wed" : 5, "Fri" : 7}'
# Given string dictionary
print("Given string : \n",stringA)
# using json.loads()
res = json.loads(stringA)
# Result
print("The converted dictionary : \n",res)

Output

Running the above code gives us the following result −

Given string :
{"Mon" : 3, "Wed" : 5, "Fri" : 7}
The converted dictionary :
{'Mon': 3, 'Wed': 5, 'Fri': 7}

With ast.literal_eval

This method from ast module works similar to the above approach. The dictionary containing string gets parsed as normal values and produces the normal dictionary.

Example

 Live Demo

import ast
stringA = '{"Mon" : 3, "Wed" : 5, "Fri" : 7}'
# Given string dictionary
print("Given string : \n",stringA)
# using json.loads()
res = ast.literal_eval(stringA)
# Result
print("The converted dictionary : \n",res)

Output

Running the above code gives us the following result −

Given string :
{"Mon" : 3, "Wed" : 5, "Fri" : 7}
The converted dictionary :
{'Fri': 7, 'Mon': 3, 'Wed': 5}
