To convert a string to a dictionary in Python, you can use the “json.loads()” function from the json module if the string is in a JSON-compliant format.
import json
str = '{"Name": "Millie", "Age": 18, "City": "Atlanata"}'
print('The JSON String is', str)
convertedDict = json.loads(str)
print("After conversion: ", convertedDict)
print(type(convertedDict))Output
The JSON String is {"Name": "Millie", "Age": 18, "City": "Atlanata"}
After conversion: {'Name': 'Millie', 'Age': 18, 'City': 'Atlanata'}
<class 'dict'>Alternate methods
Using ast.literal_eval() function
The ast.literal_eval() is a built-in Python library function that converts a string to a dict.
To use the literal_eval() function, import the ast package and use its literal_eval() method.
import ast
str = '{"Name": "Millie", "Age": 18, "City": "Atlanata"}'
print('The JSON String is', str)
convertedDict = ast.literal_eval(str)
print("After conversion: ", convertedDict)
print(type(convertedDict))Output
The JSON String is {"Name": "Millie", "Age": 18, "City": "Atlanata"}
After conversion: {'Name': 'Millie', 'Age': 18, 'City': 'Atlanata'}
<class 'dict'>Using generator expressions in Python
If we have enough strings to form a dictionary, use the generator expressions to convert the string to a dictionary.
str = "E - 11, K - 19, L - 21"
convertedDict = dict((x.strip(), int(y.strip()))
for x, y in (element.split('-')
for element in str.split(', ')))
print("Converted dict is: ", convertedDict)
print(type(convertedDict))Output
Converted dict is: {'E': '11', 'K': '19', 'L': '21'}
<class 'dict'>Conclusion
The easiest way is to use the json.loads() function to convert a valid string to a dict in Python.
