Convert Generator Object To JSON In Python
JSON (JavaScript Object Notation) is a widely used data interchange format, and Python provides excellent support for working with JSON data. However, when it comes to converting generator objects to JSON, there are several methods to consider. In this article, we’ll explore some commonly used methods.
Convert Generator Object To JSON In Python
Below, are the ways To Convert Generator objects to JSON In Python.
- Using json.dumps() Method
- Using the
yield
Keyword - Converting to a Dictionary First
Convert Generator Object To JSON Using json.dumps() Method
In this example, the below code involves the creation of a generator object using a generator expression, followed by its conversion to a list. The list is then serialized to a JSON-formatted string using `json.dumps()`. The resulting JSON data is printed, along with its data type, illustrating the transformation of the generator data into a JSON string.
Python3
import json # Sample generator object generator_obj = (x for x in range ( 5 )) print ( type (generator_obj)) # Convert the generator object to a list before JSON serialization result_list = list (generator_obj) json_data = json.dumps(result_list) print (json_data) print ( type (json_data)) |
<class 'generator'> [0, 1, 2, 3, 4] <class 'str'>
Convert Generator Object To JSON Using the yield
Keyword
In this example, below code defines a generator function `generator_to_list`, which incrementally converts a generator object into a list using the `yield` keyword. The generator object is then instantiated, and the method is applied to convert it into a JSON-formatted string using `json.dumps()`.
Python3
import json def generator_to_list(generator_obj): result_list = [] for item in generator_obj: result_list.append(item) yield item generator_obj = (x for x in range ( 5 )) print ( type (generator_obj)) # Method 5: Using yield result_generator = generator_to_list(generator_obj) json_data = json.dumps( list (result_generator)) print (json_data) print ( type (json_data)) |
<class 'generator'> [0, 1, 2, 3, 4] <class 'str'>
Convert Generator Object To JSON Convert to a Dictionary First
In this example, below code create a generator object using a generator expression, then converts it to a dictionary format with the key “data” and a list of values. This dictionary is subsequently serialized into a JSON-formatted string using `json.dumps()`. The resulting JSON data is printed along with its data type.
Python3
import json generator_obj = (x for x in range ( 5 )) print ( type (generator_obj)) # Convert to Dictionary result_dict = { "data" : list (generator_obj)} json_data = json.dumps(result_dict) print (json_data) print ( type (json_data)) |
<class 'generator'> {"data": [0, 1, 2, 3, 4]} <class 'str'>
