JSON | Python Tutorial | CodeWithHarry

JSON stands for JavaScript Object Notation. It is a built-in package provided in Python that is used to store and exchange data.

A. Converting JSON string to Python:

Example:

import json
 
# JSON String:
colors = '["Red", "Yellow", "Green", "Blue"]'
 
# JSON string to python dictionary:
lst1 = json.loads(colors)
print(lst1)

Output:

['Red', 'Yellow', 'Green', 'Blue']

B. Converting Python to JSON string:

Example:

import json
 
# python dictionary
lst1 = ['Red', 'Yellow', 'Green', 'Blue']
 
# Convert Python dict to JSON
jsonObj = json.dumps(lst1)
print(jsonObj)

Output:

["Red", "Yellow", "Green", "Blue"]

C. Conversion type:

Whenever Python objects are converted to JSON, the object type is changed to match that of JSON.

Example:

import json
 
print(json.dumps(22))               # integer
print(json.dumps(6.022))            # float
print(json.dumps("Hello World"))    # string
print(json.dumps(True))             # True
print(json.dumps(False))            # False
print(json.dumps(None))             # None

Output:

22
6.022
"Hello World"
true
false
null
