use json in python code example

Example 1: python json string to object

import json

x =  '{ "name":"John", "age":30, "city":"New York"}'
y = json.loads(x)

print(y["age"])

Example 2: python json file operations

import json # Imports the json file that we need
with open("jsonfile.json", "r") as jsonFile: # Opens Json file for reading
	data = json.load(jsonFile) # Reads Json file using json.load() method
'''
Example Json File:
[{"name": "Bill", "age": 20},
{"name": "Mary", "age": 31},
{"name": "Jake", "age": 19}]
'''
data[1]["age"] = 32 # Alters data variable
''' 
Now the data variable is:
[{"name": "Bill", "age": 20},
{"name": "Mary", "age": 32},
{"name": "Jake", "age": 19}]
'''
with open("jsonfile.json", "w") as fileJson: # Opens Json file once again
  json.dump(data, fileJson) # Replaces the Json file using json.dump() method

Example 3: json python

import json

# some JSON:
x = '{ "name":"John", "age":30, "city":"New York"}'

# parse x:
y = json.loads(x)

# the result is a Python dictionary:
print(y["age"])

Example 4: python json stringify

import json

json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
'["foo", {"bar": ["baz", null, 1.0, 2]}]'

print(json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True))
{"a": 0, "b": 0, "c": 0}

Example 5: Json in python

import json

json_file = json.load(open("your file.json", "r", encoding="utf-8"))

# For see if you don't have error:
print(json_file)

Example 6: python to json

# a Python object (dict):
x = {
  "name": "John",
  "age": 30,
  "city": "New York"
}

# convert into JSON:
y = json.dumps(x)
