python make json 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: 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 3: python import json data

# Basic syntax:
import ast
# Create function to import JSON-formatted data:
def import_json(filename):
  for line in open(filename):
    yield ast.literal_eval(line)
# Where ast.literal_eval allows you to safely evaluate the json data.
# 	See the following link for more on this:
# 	https://stackoverflow.com/questions/15197673/using-pythons-eval-vs-ast-literal-eval
        
# Import json data
data = list(import_json("/path/to/filename.json"))

# (Optional) convert json data to pandas dataframe:
dataframe = pd.DataFrame.from_dict(data)
# Where keys become column names

Example 4: json.loads

>>> import json
>>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]')
['foo', {'bar': ['baz', None, 1.0, 2]}]
>>> json.loads('"\\"foo\\bar"')
'"foo\x08ar'
>>> from io import StringIO
>>> io = StringIO('["streaming API"]')
>>> json.load(io)
['streaming API']

Example 5: json.dumps python

example={
    "Playlists": [
        "Default"
    ],
    "Default": [
        "Resources\\Media\\C.mp3",
        "Resources\\Media\\K.mp3"
    ]
}
import json
json_file_path=input('Enter the path: ')
with open(json_file_path,'w') as hand:
     json.dumps(example,hand,indent=4) 
'''# dict,file_pointer,indentation'''

Example 6: Json in python

{
	"Icons":{
    	"app icon": "your icon.ico",
        "eg icon": "eg.ico"
	}
