Example 1: print json python
import json
uglyjson = '{"firstnam":"James","surname":"Bond","mobile":["007-700-007","001-007-007-0007"]}'
#json.load method converts JSON string to Python Object
parsed = json.loads(uglyjson)
print(json.dumps(parsed, indent=2, sort_keys=True))
Example 2: load json
import json
with open('data.txt') as json_file:
data = json.load(json_file)
Example 3: 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 4: python dict to json
# app.py
import json
appDict = {
'name': 'messenger',
'playstore': True,
'company': 'Facebook',
'price': 100
}
app_json = json.dumps(appDict)
print(app_json)
Example 5: 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 6: 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'''
