json_example.py

>>> import json
>>> colors = ["red","green","blue"]
>>> colors_in_json = json.dumps(colors)
>>> colors_in_json
# ["red","green","blue"]

Parse JSON object

json_example.py

>>> import json
>>> capitals_in_json = [{"country":"Vietnam","capital":"Hanoi"},{"country":"France","capital":"Paris"}]
>>> capitals = json.loads(capitals_in_json)
>>> capitals 
# [{"country":"Vietnam","capital":"Hanoi"},{"country":"France","capital":"Paris"}]

Write to .json file

json_example.py

import json
colors = ["red","green","blue"]
with open("colors.json","w") as file:
    json.dump(colors)

Read from .json file

import json
with open("colors.json") as file:
