How To Convert Following String To Json In Python

How can i convert the below string to JSON using python? str1 = '{'a':'1', 'b':'2'}'

Solution 1:

The json library in python has a function loads which enables you to convert a string (in JSON format) into a JSON. Following code for your reference:

import json

str1 = '{"a":"1", "b":"2"}'
data = json.loads(str1)

print(data)

Note: You have to use ' for enclosing the string, whereas " for the objects and its values.

Solution 2:

The string in OP's question is not JSON because the keys and values are enclosed by single-quotes. The function ast.literal_eval can be used to parse this string into a Python dictionary.

import ast
str1 = "{'a':'1', 'b':'2'}"
d = ast.literal_eval(str1)
d["a"]  # output is "1"

Other answers like https://stackoverflow.com/a/58540688/5666087 and https://stackoverflow.com/a/58540879/5666087 were able to use the json library because they changed str1 from "{'a':'1', 'b':'2'}" to '{"a":"1", "b":"2"}'. The former is invalid JSON, whereas the latter is valid JSON.

Solution 3:

import json

str1 = '{"a":"1", "b":"2"}'

jsonData = json.loads(str1)

print(jsonData["a"])
