To convert a tuple to JSON (JavaScript Object Notation) in Python, use the json.dumps() method. The json.dumps() method serializes objects (like tuples, lists, dict, etc.) into a JSON-formatted string and returns it.

 

import json

my_tuple = ("Apple", "Meta", "Tesla")

print(my_tuple)
# Output: ('Apple', 'Meta', 'Tesla')

print(type(my_tuple))
# Output: <class 'tuple'>

# Conversion to JSON
json_data = json.dumps(my_tuple)

print(json_data)
# Output: '["Apple", "Meta", "Tesla"]'

print(type(json_data))
# Output: <class 'str'>

In the above code, we first define a tuple with three elements and then print its type.

In the next step, we used the json.dumps() method and pass the “my_tuple” as an argument that returns a JSON-formatted string. Note that even if the output is JSON-formatted, its type in Python is string.

Nested Tuple

If the tuple is nested, it is recursively converted into nested lists.

import json

nested_tuple = ("x", (11, 21, 31), ("b", "c"))

print(nested_tuple)
# Output: ('x', (11, 21, 31), ('b', 'c'))

print(type(nested_tuple))
# Output: <class 'tuple'>

# Conversion to JSON
json_data = json.dumps(nested_tuple)

print(json_data)
# Output: '["x", [11, 21, 31], ["b", "c"]]'

print(type(json_data))
# Output: <class 'str'>

In this code, the nested tuple in the input is (11, 21, 31), and the output string contains [11, 21, 31] as a list.

Using different datatypes

Here’s a table that outlines the default conversions performed by the JSON module:

Python	JSON
dict	Object
tuple	Array
list	Array
str	String
number – int, long	number – int
float	number – real
True	true
False	false
None	null

import json

my_tuple = ("Apple", 4, 2.34, True)

print(my_tuple)
# Output: ('Apple', 4, 2.34, True)

print(type(my_tuple))
# Output: <class 'tuple'>

json_data = json.dumps(my_tuple)

print(json_data)
# Output: '["Apple", 4, 2.34, true]'

print(type(json_data))
# Output: <class 'str'>

That’s all!
