Python | Ways to convert string to json object

Data send and get generally in a string of dictionary(JSON objects) forms in many web API’s to use that data to extract meaningful information we need to convert that data in dictionary form and use for further operations. Let’s see some ways to convert string to json. 
Method #1: dict object to string object using json.loads 

Output:

initial 1st dictionary {'manjeet': 10, 'nikhil': 1, 'akshat': 15, 'akash': 5}
type of ini_object <type 'str'>
final dictionary {'nikhil': 1, 'manjeet': 10, 'akshat': 15, 'akash': 5}
type of final_dictionary <type 'dict'>

Method #2: str object to dict object using eval() 

Output:

initial 1st dictionary {'nikhil': 1, 'akash' : 5, 'manjeet' : 10, 'akshat' : 15}
type of ini_object <class 'str'>
final dictionary {'nikhil': 1, 'manjeet': 10, 'akash': 5, 'akshat': 15}
type of final_dictionary <class 'dict'>

Method #3:  Using the ast.literal_eval function

Initial string dictionary:  {"name": "John", "age": 30, "city": "New York"}
Final dictionary:  {'name': 'John', 'age': 30, 'city': 'New York'}
<class 'dict'>

In the above code, we are using the ast.literal_eval function to parse a string representation of a dictionary and create a Python dictionary object. The initial string is a JSON object representation of a dictionary with three properties: “name”, “age”, and “city”. The ast.literal_eval function parses the string and creates a Python dictionary object with the same properties and values. The resulting dictionary object has a type of dict. We can then access the properties of the dictionary object using standard dictionary access notation (e.g. dict_obj[“name”]).

This demonstrates that the ast.literal_eval function was able to successfully parse the input string and create a Python dictionary object with the same properties and values as the original JSON object.
