Python Serialize Object to JSON String

Python Python JSON Python Serialize

In this Python tutorial we will learn how to serialize a Python object into a JSON string and go through different code examples in Python.

First step we need to import json package in source file.

import json

To serialize a Python object into JSON string we will use json.dumps() method. Below are list of different example of using json.dumps() method.

Serialize Python dict Object to JSON String

user = {"firstName": "Kathy", "lastName": "Wells"}

json_user = json.dumps(user)

print(json_user)

Serialize Python list Object to JSON String

languages = ['Python', 'Java', 'C#', 'C++']

json_languages = json.dumps(languages)

print(json_languages)

Serialize Python tuple Object to JSON String

skills = ('Web Development', 'Mobile Development', 'Agile')

json_skills = json.dumps(skills)

print(json_skills)

Serialize Python string Object to JSON String

message = "Hello from toricode.com"

json_message = json.dumps(message)

print(json_message)

Serialize Python int Object to JSON String

points = 7

json_points = json.dumps(points)

print(json_points)

Serialize Python float Object to JSON String

price = 45.78

json_price = json.dumps(price)

print(json_price)

Serialize Python True Object to JSON String

json_true = json.dumps(True)

print(json_true)

Serialize Python False Object to JSON String

json_false = json.dumps(False)

print(json_false)

Serialize Python None Object to JSON String

json_none = json.dumps(None)

print(json_none)

The complete Python code of this tutorial.

import json

# Serialize Python dict Object to JSON String

user = {"firstName": "Kathy", "lastName": "Wells"}

json_user = json.dumps(user)

print(json_user)

# Serialize Python list Object to JSON String

languages = ['Python', 'Java', 'C#', 'C++']

json_languages = json.dumps(languages)

print(json_languages)

# Serialize Python tuple Object to JSON String

skills = ('Web Development', 'Mobile Development', 'Agile')

json_skills = json.dumps(skills)

print(json_skills)

# Serialize Python string Object to JSON String

message = "Hello from toricode.com"

json_message = json.dumps(message)

print(json_message)

# Serialize Python int Object to JSON String

points = 7

json_points = json.dumps(points)

print(json_points)

# Serialize Python float Object to JSON String

price = 45.78

json_price = json.dumps(price)

print(json_price)

# Serialize Python True Object to JSON String

json_true = json.dumps(True)

print(json_true)

# Serialize Python False Object to JSON String

json_false = json.dumps(False)

print(json_false)

# Serialize Python None Object to JSON String

json_none = json.dumps(None)

print(json_none)

Execute the Python code above you will get the result as below.
