How to convert a Tuple to JSON in Python

Convert a Tuple to JSON in Python #

Use the json.dumps() method to convert a tuple to JSON, e.g. json_str = json.dumps(my_tuple). The json.dumps() method converts a Python object to a JSON formatted strings and supports tuple to JSON array conversion.

import json

my_tuple = ('one', 'two', 'three')

json_str = json.dumps(my_tuple)

print(json_str)  # 👉️ '["one", "two", "three"]'
print(type(json_str))  # 👉️ <class 'str'>

We used the json.dumps method to convert a tuple to a JSON string.

The json.dumps method converts a Python object to a JSON formatted string.

Python tuples are JSON serializable, just like lists or dictionaries.

The JSONEncoder class supports the following objects and types by default.

The process of converting a tuple (or any other native Python object) to a JSON string is called serialization.

Whereas, the process of converting a JSON string to a native Python object is called deserialization.

When you parse the JSON string into a native Python object, you get a list back.

import json

my_tuple = ('one', 'two', 'three')

# 👇️ convert tuple to JSON
json_str = json.dumps(my_tuple)

print(json_str)  # 👉️ '["one", "two", "three"]'
print(type(json_str))  # 👉️ <class 'str'>

# --------------------------------

# 👇️ parse JSON string to native Python object
parsed = json.loads(json_str)

print(parsed)  # 👉️ ['one', 'two', 'three']
print(type(parsed))  # 👉️ <class 'list'>

Notice that we got a list object after parsing the JSON string. This is because both list and tuple objects get converted to a JSON array when serialized.

You can use the tuple() class to convert the list to a tuple after parsing the JSON string.

Copied!
import json

my_tuple = ('one', 'two', 'three')

json_str = json.dumps(my_tuple)

print(json_str)  # 👉️ '["one", "two", "three"]'
print(type(json_str))  # 👉️ <class 'str'>

# --------------------------------

# 👇️ convert to tuple
parsed = tuple(json.loads(json_str))

print(parsed)  # 👉️ ('one', 'two', 'three')
print(type(parsed))  # 👉️ <class 'tuple'>

The example uses the tuple() class to convert the list we got after parsing the JSON string.

Tuples are very similar to lists, but implement fewer built-in methods and are immutable (cannot be changed).
