Convert Unicode String to Dictionary in Python

Python’s versatility shines in its ability to handle diverse data types, with Unicode strings playing a crucial role in managing text data spanning multiple languages and scripts. When faced with a Unicode string and the need to organize it for effective data manipulation, the common task is converting it into a dictionary. In this article, we will see how to convert a Unicode string to a dictionary in Python.

Convert A Unicode String To A Dictionary In Python

Below are some ways by which we can convert Unicode string to a dictionary in Python:

Convert A Unicode String To A Dictionary Using json.loads()

Utilizing the `json` module’s `loads()` function is a straightforward and effective way to convert a JSON-formatted Unicode string into a Python dictionary.

Python3

import json

unicode_string = '{"name": "John", "age": 30, "city": "New York"}'
print(type(unicode_string))

result_dict = json.loads(unicode_string)
print(type(result_dict))
print(result_dict)

Output

<class 'str'>
<class 'dict'>
{'name': 'John', 'age': 30, 'city': 'New York'}

Unicode String to Dictionary Using ast.literal_eval() Function

The `ast.literal_eval()` function is used as a safer alternative to `eval()`, allowing the evaluation of literals and converting the Unicode string to a dictionary.

Python

import ast

unicode_string = '{"key1": "value1", "key2": "value2", "key3": "value3"}'
print(type(unicode_string))

result_dict = ast.literal_eval(unicode_string)
print(type(result_dict))
print(result_dict)

Output

<type 'str'>
<type 'dict'>
{'key3': 'value3', 'key2': 'value2', 'key1': 'value1'}

Convert Unicode String to Dictionary Using yaml.safe_load() Function

The `yaml.safe_load()` function can handle YAML-formatted Unicode strings, providing a versatile alternative for converting data into a dictionary.

Python

import yaml

unicode_string = "name: Alice\nage: 25\ncity: Wonderland"
print(type(unicode_string))

result_dict = yaml.safe_load(unicode_string)
print(type(result_dict))
print(result_dict)

Output:

<type 'str'>
<type 'dict'>
{'name': 'Alice', 'age': 25, 'city': 'Wonderland'}

Conclusion

Converting a Unicode string to a dictionary in Python is a fundamental operation when dealing with textual data. Leveraging the `json` module simplifies this process, providing a standardized and reliable approach. Understanding the principles of Unicode strings and dictionaries, along with the additional considerations discussed, empowers developers to handle diverse data formats efficiently. Whether parsing API responses or processing user inputs, the ability to convert Unicode strings to dictionaries is a valuable skill for any Python programmer.
